@kulagowskim you've done it, or is there any question?
@luizanyn if you have to return a boolean, generally it isn't
@Lumexralph how its work :D
@nghm what do you want to know?
@kulagowskim you want to know how it works?
Hey guys, I am really struggling with Lesson 217 Javascript Profile Lookup. Profile Lookup
We have an array of objects representing different people in our contacts lists.
A lookUpProfile function that takes firstName and a property (prop) as arguments has been pre-written for you.
The function should check if firstName is an actual contact's firstName and the given property (prop) is a property of that contact.
If both are true, then return the "value" of that property.
If firstName does not correspond to any contacts then return "No such contact"
If prop does not correspond to any valid properties then return "No such property"
@Lumexralph yea i do this request but i don
t know how its work
Can anyone shed a light on this
@Lumexralph
JSON.stringify do something?
@Lumexralph well thanks anyway!

@kulagowskim
arr is an array push(item) is a method that puts the the value as the last element of an array, item is added to array arr...... shift()is also a method of an array that removes the first element of array arr and returns it
@waynebunch :+1:
@inagreen there are several ifs there, try creating an if/else structure
My advice, review all past object related challenges if you don't know how to do some of those things
contacts is an array, so you'll need a loop to go through the contacts

@Lumexralph if i have array a = [1,2,3,4] and i doing on it a.shift() i get [2,3,4] or [1] ?
Hi Diego, I guessed as much but I actually tried to focus on using while loop and hasOwnProperty but not getting past addressing the properties of the object in the array
good evening coders!

@Lumexralph http://www.w3schools.com/jsref/jsref_shift.asp
@Lumexralph no way xD
function lookUpProfile(firstName, prop){
// Only change code below this line
for(var i=0;i<contacts.length;i++){
if(firstName==contacts[i].firstName){
if(contacts[i].hasOwnProperty(prop)){
return contacts[i].prop;

prop is a variable you can't use dot method use [ ]

@inagreen you can use a while loop if you want too
@Lumexralph arr = [1,2,3] | arr.shift() give me [1] | but new arr is [2,3] yes?
@Chrono79 Im gonna try this as well I think I wasnt using the right syntax when pinpointing to specific prop of the object in the array too
@kulagowskim yes, it removes the first element so
arr becomes [2, 3]

hi camps
why here cannot use else? How to fix my code
@kenbbetter
checkProp is a variable not a string
@cassv24
"This Is A Test".match(/( [A-Z])|(^[A-Z])/g)
Working on Switch Statement and I don't see where I'm making my mistake:
function caseInSwitch(val) {
var answer = "";
switch (val) {
case 1 :
console.log("alpha");
break;
case 2 :
console.log("beta");
break;
case 3 :
console.log("gamma");
break;
case 4 :
console.log("delta");
break;
}
return answer;
}
caseInSwitch(1);
@kenbbetter "checkProp" is a string in the function call - it should be the variable
@kmcrayton7 assign the strings to result for each cases
@sjames1958gm great (y)
@kmcrayton7 See that
return answer; at the end - you need to set answer to the string value
@kenbbetter
if (myObj.hasOwnProperty("checkProp")=== true);{ remove the semicolon here.
that part works..
only have problem in "Not Found"
@mitron6 he needs to make
checkProp a variable there and === true is not needed @kenbbetter
@Lumexralph @sjames1958gm I understand what you are saying but how?
// Setup
var myStr = "Jello World";
// Only change code below this line
myStr = "Hello World";
myStr[0] = "Hello World"; // Fix Me
@kmcrayton7 Use assignment instead of console.log()
@andercodder You need to remove the line with
a severe enough error that the tests do not run
myStr[0] that line causesa severe enough error that the tests do not run
someone help me why i get the error TypeError: Cannot assign to read only property '0' of string 'Hello World'
@kmcrayton7 like this
answer = "alpha" ditto for the remaining cases
@andercodder That is the essence of the challenge - you cannot set the individual characters
of a string they are read-only so when you try to assign to myStr[0] TypeError
of a string they are read-only so when you try to assign to myStr[0] TypeError
// Setup

@kenbbetter You made neither of the changes recommended
use checkProp not "checkProp" and remove that trailing semicolon
use checkProp not "checkProp" and remove that trailing semicolon
@kmcrayton7 For many of the challenges they will provide the return variable with var and return
all you need to do is assign to the variable in your code.
all you need to do is assign to the variable in your code.
@kenbbetter
checkProp in hasOwnProperty function should be a variable not string and remove the ;
var myObj = {
top: "hat",
bottom: "pants"
};
myObj.hasOwnProperty("top"); // true
myObj.hasOwnProperty("middle"); // false
@kenbbetter add
return "Not Found"; in an else or simply after the return you hvae
@sjames1958gm
why here is
top not top?
``top ``
@sjames1958gm this is what confuses me a lot of the time. I'm never sure what to change when they provide content
@kenbbetter because it is a variable passed to the function.
@kmcrayton7 If they have comments with don't change below or above then those should be heeded - otherwise you
should have free reign - later challenges give you less and less of that help
should have free reign - later challenges give you less and less of that help
you made me confused
@kenbbetter because it's a valid property in myObj, here you're dealing with a variable/parameter
checkProp from your function
@kenbbetter use
checkProp not "checkProp"
@kenbbetter
var myObj = {
top: "hat",
bottom: "pants"
};
var topvar = "top"
myObj.hasOwnProperty("top"); // true
myObj.hasOwnProperty(topvar); // true
myObj.hasOwnProperty("middle"); // false
// Setup
var myObj = {
gift: "pony",
pet: "kitten",
bed: "sleigh"

// Your Code Her
if (myObj.hasOwnProperty(checkProp));
return myObj[checkProp];
else {
return "Not Found";
}
}
// Test your code by modifying these values
checkObj("pet");
is this what you mean?
@sjames1958gm
function lookUpProfile(firstName, prop){
for(var i=0;i<contacts.length;i++){
if(contacts[i].firstName==firstName){
if(contacts[i].hasOwnProperty(prop)){
return contacts[i][prop];
}else{
return "No such property";
}
}else{
return "No such contact";
}
}
}
@kenbbetter Yes, but you need to remove that ';' at the end of the 'if' line
@way3edgyentertainment How can you return no such contact without first looking through all the contacts.
// Setup
var myObj = {
gift: "pony",
pet: "kitten",
bed: "sleigh"
};
function checkObj(checkProp) {
// Your Code Her
if (myObj.hasOwnProperty(checkProp));
return myObj[checkProp]
else
return "Not Found";
}
// Test your code by modifying these values
checkObj("gift");
@way3edgyentertainment your loop still won't run more than once (return exits the loop and the function)
@kenbbetter remove the semicolon at the end of the if parentheses()

when need to combine several knowledge
mess up
function convertToF(celsius) {
var fahrenheit;
// Only change code below this line
fahrenheit =9/5+32 celsius ;
// Only change code above this line
return fahrenheit;
}
// Change the inputs below to test your code
convertToF(30);
pls give me a proper way to write this code
damn always eror
@rusdie what's the formula?
9/5+32 celsius this is not valid syntax and doesn't match the formula C * 9/5 + 32
@rusdie Your formula is incorrect.
the didnt give any
they told me to create from scratch
challange 139
@way3edgyentertainment return no such contacts after the loop is done looking through contacts
@rusdie The formula is in the second paragraph
@rusdie you can also search the formula
Variable myStr should contain the string: I am a "double quoted" string inside "double quotes". var myStr = "I am a\"double quoted\" string inside of \"double quotes\"."; /
@TheBillyTowers
"I am a\"double quoted\" string inside of \"double quotes\"."; /
celsius*9/5+32 = fahrenheit
like that ?
@rusdie Flip it around and you're good
but still they say invalid assignment left-hand side
what code is missing
Hence why I'm telling you to flip it around
flip ?
fahrenheit should be on the left, not the right
ah
i will try
@rusdie To test 82 degrees F = 28 degrees C

@andercodder String concatenation with variables parameters
@andercodder Gist by revisualize / FreeCodeCamp - Word_Blanks.js
@andercodder Learn about parameters and arguments and you cannot fail
still noobs
hahahha ask the pro
What is the difference between String Concatenation vs. String Interpolation?
@rusdie Don't ask the pro. Become the pro.
good advice my bro
@itsthomas Let me google that. It will take me a few seconds to find you an answer.
@revisualize I tried to google it, but couldn’t find anything which explains the difference.
I <3 that google thing. It makes me look smarter than I am.
Are the following both "string interpolation"?:
var favoriteAnimal = "Horse";
console.log("My favorite animal: “ + favoriteAnimal);var favoriteAnimal = "Horse";
console.log("My favorite animal: " , favoriteAnimal);
The result is the same.
@itsthomas I have no idea.
@itsthomas Neither
@mitron6 what are they then?
String Concatenation?
@itsthomas The first is a string concatenated and the second is a string and a variable
@itsthomas The top one is string concatenation.
One of the lession in CodeAcademy about JavaScript explains that the first one is string interpolation:
We can use the + operator from earlier to interpolate (insert) a variable into a string, like this:
var myPet = 'armadillo';
console.log('I own a pet ' + myPet + '.');
// Output: 'I own a pet armadillo.’
@itsthomas Your two code blocks do NOT ouput the same thing.
That is String Concatenation.
Ya, they are incorrectly calling it interpolation
Codecademy is wrong.
@JLuboff Thanks
itsthomas sends brownie points to @jluboff :sparkles: :thumbsup: :sparkles:
:cookie: 566 | @jluboff |http://www.freecodecamp.com/jluboff
@revisualize the output fot both is the same. I just tested again.
@itsthomas
They do NOT output the same thing.
why does it return "cannot read property 'length' of null
" when i plug str = "california"?
" when i plug str = "california"?
function translatePigLatin(str) {
var vowels = /[aeiou]/g;
if(str[0].match(vowels).length > 0){
var arr = str.split("");
var newArr = arr.push("w", "a", "y");
return arr.join("");
}else{
return true;
}
}
translatePigLatin("eight");
@greedylan www.pythontutor.com/javascript.html
@greedylan What happens if you don't have a vowel? You'd be returning 0, can't get length of 0
guys
i did this
function wordBlanks(myNoun, myAdjective, myVerb, myAdverb) {
var result = "";
// Your code below this line
result = + myNoun + " " +myAdjective + " " + myVerb + " " + myAdverb + " ";
// Your code above this line
return result;
}
// Change the words here to test your function
wordBlanks("dog", "big", "ran", "quickly");

@rusdie your strings are wrong
@RhinoTek use an if
@RhinoTek
.hasOwnProperty() outputs a boolean. Do you know what a boolean value is?
@revisualize my also have space in it, isn't?
i know my string is the problem
Nice to see you again. btw,

how should i write it ?
@rusdie Correctly.
@rusdie
firstLine is not the same as FirstLine
secondLine is not the same as SecondLine
thirdLine is not the same as ThirdLine
firstLine is not the same as FirstLine
secondLine is not the same as SecondLine
thirdLine is not the same as ThirdLine
Strings are immutable and case sensitive.
@revisualize camelCase overdose ;)
var myStr="FirstLine\n\SecondLine\ThirdLine\r";
@rusdie Great.
still nothing dude
what you give to me, is same as i write... @revisualize
Now you're escaping the carriage-return in the wrong spot.

@rusdie some escaped sequence is misplaced there

@revisualize i am seeking for your help bro
@kenbbetter Sorry.

@kenbbetter If your properties have spaces in them you cannot use dot notation. You have to use bracket notation.
i said what you ask me to do, is same as i write
oh
@kenbbetter Did you try
["glove box"]
@kenbbetter you don't need to use the bracket notation with inside, but, you should use it with "glove box": https://www.freecodecamp.com/challenges/accessing-objects-properties-with-bracket-notation

@Chrono79 but that is the requirement of this challenge
@kenbbetter no, it says you have to use both, but you used them not where it's needed
.inside and ["inside"] are both valid
.glove box is not valid
["glove box"] is valid
.inside and ["inside"] are both valid
.glove box is not valid
["glove box"] is valid
@RhinoTek hasOwnProperty returns true or false . So u have to create a variable that stores the returned boolean value. This variable can be used to create conditional statements.
var gloveBoxContents = myStorage.car.inside.["glove box"]; // Change this line
@Chrono79 @JohnnyBizzel is this what you mean?
@kenbbetter remove the . before the bracket notation.
@kenbbetter almost ;)

@carpben you need a loop or something similar and then you have to build a new string with the capitalized initial plus the rest of the word
@avogadromert why are you using other vars?
varyes is not even defined in your first line
varyes is not even defined in your first line
@Chrono79 Yes, I thought of this option, but a quick search reveals there is a simpler solution, involoving str replacement using regularexpersion such as /something/.
@carpben simpler depends entirely on your knowledge on regexp
@Chrono79 could you tell me what to basically change there cause i think im just thinking to complicated.
@avogadromert see the example on i and read the instructions carefully, you only need one line and use myVar and ++

\SecondLine\
ThirdLine

@neozane1 the inner loop is not ok
ok what did i miss
@neozane1 look specially at this
j<arr.length
is following the correct way to create a Regexp for consonant? english letters only but without vowels
var consonant = /a-z&&[^aeiou]/@Chrono79 how do we do it ?
@greedylan not
ok thanks @Chrono79

is that for pig latin? @greedylan
@Chrono79 YES
how do i assign 5 to oopsGlobal with out using the var ```
// Declare your variable here
var myGlobal = 10;
function fun1() {
// Assign 5 to oopsGlobal Here
oopsGlobal(5);
}
// Only change code above this line
function fun2() {
var output = "";
if (typeof myGlobal != "undefined") {
output += "myGlobal: " + myGlobal;
}
if (typeof oopsGlobal != "undefined") {
output += " oopsGlobal: " + oopsGlobal;
}
console.log(output);
}
@greedylan I checked for Vowel with this basic regex:
// test regex for Vowel:
var patt = /A|a|E|e|I|i|O|o|U|u/;// Declare your variable here
var myGlobal = 10;
function fun1() {
// Assign 5 to oopsGlobal Here
oopsGlobal(5);
}
// Only change code above this line
function fun2() {
var output = "";
if (typeof myGlobal != "undefined") {
output += "myGlobal: " + myGlobal;
}
if (typeof oopsGlobal != "undefined") {
output += " oopsGlobal: " + oopsGlobal;
}
console.log(output);
}
@greedylan I would test for vowels and in the else do what you need to do for consonants
and how would i do it with a var
@JohnnyBizzel i modifier is your friend ;)
@Chrono79 yes I actually pass the test but im just curious how we write for the consonant. messing with regex101.com but no clue
if you're sure they're only letters, then /[^aeiou]/i is fine (i modifier is optional because all tests are lowercase)
thanks @Chrono79 i just realized i didnt put a j<arr[i].length in and fixed it lol
neozane1 sends brownie points to @chrono79 :sparkles: :thumbsup: :sparkles:

Can anyone give me a few hits.

@greedylan in that case you should list all the consonants. They're 21 after all
@scoutsnknives the idea is to add up the variables to make a "sentence", so like
"My " + myAdjective + " " + myNoun results in "My big dog"
you at least need to have spaces between the words

having trouble with this challenge
can any fellow coders help me
@keewhy whats the prob bob?
I believe my code or wrong or this challenge is bugged
have tried numerous ways cant seem to get her to work
@keewhy you can't just copy the instructions, you need to look at the table above
first time ive had to use the help section . I do not see instructions for linking the code :(.
@keewhy you have to copy and paste, the button with the M on it (in the chat box) has formatting help
var myStr = " \"FirstLine\"\n \'SecondLine'\ \r\"ThirdLine"; is my current code for that challenge.
@keewhy YOu should only have one pair of quotes for the entire string remove the spaces
Set remainder equal to the remainder of 11 divided by 3 using the remainder (%) operator.
hi guys I got stuck with this one could anyone help
I tried that originally but with spaces. Silly me. Thank you my friend!.

Hey going through js beginner, is there any reason or benefit to assigning variables without using var? The walkthrough i'm at literally says to declare all variables with var as a general good practice then to pass this section i can't use var.
does not using var create the variable as global no matter what?
@doodleslr yeah you can accidentally create a global within a function and it can have unintended side effects
@doodleslr I've seen a situation here where a global was accidentally created within a function and reused, having a value set from a previous call
so the general rule is mostly to always declare variables with var to avoid those problems later?
I think it's a good habit to get into ... tracking down the scope of variables can be tricky if there's lots of globals
yeah, that sounds like an easy way to skip a lot of headache, thanks for the help @eeflores !

for the profile lookup JS challenge why does
function lookUpProfile(firstName, prop){
if(contacts.hasOwnProperty(firstName)){
if(contacts.hasOwnProperty(firstName.prop)){
return contacts.firstName.prop;
}else{
return "No such property";
}
}else{

if(contacts.hasOwnProperty(firstName.prop)){
return contacts.firstName.prop;
}else{
return "No such property";
}
}else{
return "No such contact";
}
}
this not work
take into account that the if loops are nested
little bit confused on the nesting for loops problem
function multiplyAll(arr) {
var product = 1;
// Only change code below this line
// Only change code above this line
return product;
}
// Modify values below to test your code
multiplyAll([[1,2],[3,4],[5,6,7]]);
firstname and prop arent strings
why set product equal to 1??
Comparison with the Greater Than Or Equal To Operator......I'm stuck lol
Yes they are not strings but they should be able to be returned and looked up by .hasOwnProperty and also should be able to be returned
It seems really simple and I feel dub for not understading it
Not quite understanding why that code would not work
@dd-beanz youre also not iterating through the arrays
theres quite a lot wrong with your code
> is greater than and === is equal to
would map be sufficient for iterating through?
not really
use a for loop
Okay, so for that problem there needs to be iteration and also checks for hasOwnProperty I am guessing?
yes
Ok thank you HeebieGeeBee!
var myStr = "This is the first sentence." += "this is the second sentence." ; Where am i going wrong here guys. Thanks.
why the = sign? @keewhy
Build myStr over several lines by concatenating these two strings:
"This is the first sentence. " and "This is the second sentence." using the += operator.
"This is the first sentence. " and "This is the second sentence." using the += operator.
and sentences usually start with capital letters
@keewhy change
+= to +
oh, nevermind
myStr += "secondSentence";
tried that didnt work
it says over several lines
does anyone have experience with the nesting for loops?
I think its to do with the spacing trying to fix now.
@keewhy you need to write code over a few lines
so the first line will be something like myStr = "This is the first sentence. "
then you have to do another line where you add the second line to the existing myStr variable
think how you would do that using +=
@keewhy and yeah, possibly put a space after the first full stop on the first string ...
whats the problem @johnnunns
ok well i go back to laying down then
function multiplyAll(arr) {
var product = 1;
// Only change code below this line
for(var i =0; i<arr.length; i++){
for(var j = 0; j<arr.length[i]; j++){
console.log(product*arr[i][j]);
}
}
// Only change code above this line
return product;
}
// Modify values below to test your code
multiplyAll([[1,2],[3,4],[5,6,7]]);
I'm way off I feel
thats alright
you have a nest loop
nested
// Declarations
var studlyCapvar = 10;
var properCamelcase = "A String";
var titleCaseover = 9000;
// Assignments
studlyCapvar = 10;
properCamelcase = "A String";
titleCaseover = 9000;
dont know whats wrong
right
which to be honest I'm confused why I'd even be nesting a loop. Just something you have to do when it's a multi array?
guys whats wrong with my code?
yes @johnnunns
its level 126
what do you even want to do? @Farzan-Hashmi
properCamelCase lol
:worried:
so funny
:)
Hey i suck i just noticed it lol
dont worry we all do

Not sure how far off I am but I'm really not grasping the concept here
@johnnunns
product is a number, you can't use .push() on a number. But you're close.
@cesarecaravaggio Without looking at the challenge, I believe it wants you to create a sentence using the arguments that are passed to the function. You may try making multiple variables. And review string concatenation.
@Manish-Giri
i tryed a for loob. but i endet up finding a solution on google :(
i tryed a for loob. but i endet up finding a solution on google :(
@johnnunns instead of using
.push(), you need to multiply product with the current number in the nested loop
@cburros i figured it out, it just took me 2 nights to do it haha
@cesarecaravaggio Good job sticking with it.
@johnnunns
_____* arr[i][j];
yeah I wrote out console.log(product*arr[i][j] initially but still missed it

@johnnunns don't initialize your product variable.
where it says var product = 1?
because that wasn't my doing
Oh, my bad. Sorry I'm tired
j<arr.length[i]
is wrong
@cburros no problem, I was confused by it though
it should be
length of arr[i]

Hey anybody really good with jasmine testing with javascript?
Hi everyone, not sure why the code marked in blue fails to deliver. Any ideas?
@carpben Strings are immutable, you can't change a character inside of it
https://www.freecodecamp.com/challenges/understand-string-immutability have you done this challenge yet?
yes I know. but I didn't change the content of a string, but an element in an array. name[0]=name[0].toUpperCase();
on the right hand we get 'B', and then we change the first object of the array.
name isn't an array
you set it to a string:
name = 'Ben';
OOPS
@johnnunns
contacts is an array
yeah I wasn't exactly sure how to return that
@johnnunns Let's say we have an array:
How do you access
var contacts = [ "A" , "H" , "S" , "K" ];How do you access
"H"?
contacts[1]
@johnnunns Let's say you have an object.
// var name = "Happy";
var myFriend = {
"firstName": "Happy",
"lastName": "Feet",
"number": "-i",
"likes": ["rhythm", "dancing", "soul"]
}How do you access the firstName of myFriend?
hi, pls look this problem

@Ammy3165 you should review the structure of
switch/case
is it the same way??
variable in the function call.
I got error message, a is not defined
there shouldn't be if statements in side your switch statement @Ammy3165, take a look at how to construct case/switch statements again
@johnnunns No.
myFriend.firstName[]
thanks everybody
@johnnunns Not quite.
what you want to do inside of case/switch is set the answer variable, not return anything also.
@johnnunns You don't need the [] at the end.
@johnnunns Ready for the next question?
yes
@johnnunns Let's say we have an array:
var contacts = [ { f: "A" } , { f: "H" } , { f: "S" } , { f: "K" } ];How do you output "H"?

@cesarecaravaggio hmm.. just compare this two arrays:
arr1 = [a, b, c];
arr2 = [[X,Y,Z],[apple, banana]];it is important to note that each element in an array are indexed starting from ZERO.
arr1[0] will return just 'b'
whereas arr2[0] will return the first element [X,Y,Z] of the main array which only consists of two elements i.e. [X,Y,Z] and [apple,banana]
therefore arr2[0][1] will check the 2nd element in array [X,Y,Z] which is just 'Y'

Very confused why the values below work but I not the others
//Setup
var contacts = [
{
"firstName": "Akira",
"lastName": "Laine",
"number": "0543236543",
"likes": ["Pizza", "Coding", "Brownie Points"]
},
{
"firstName": "Harry",
"lastName": "Potter",
"number": "0994372684",
"likes": ["Hogwarts", "Magic", "Hagrid"]
},
{
"firstName": "Sherlock",
"lastName": "Holmes",
"number": "0487345643",
"likes": ["Intriguing Cases", "Violin"]
},
{
"firstName": "Kristian",
"lastName": "Vos",
"number": "unknown",
"likes": ["Javascript", "Gaming", "Foxes"]
}
];
function lookUpProfile(firstName, prop){
// Only change code below this line
for(i=0;i<contacts.length;i++){
if(contacts[i].firstName === firstName && contacts[i].hasOwnProperty(prop) ){
return contacts[i][prop];
} else if( contacts[i].firstName!== firstName){
return "No such contact";
} else {
return "No such property";
}
// Only change code above this line
}
}
// Change these values to test your function
lookUpProfile("Akira", "likes");
Akira likes works. But when I change to Harry it brings up no such contact
@way3edgyentertainment ?
@johnnunns you'll want to move the no such contact return outside of the for loop
@TracesOfNuts I'm not sure how to get the replace to work with all special characters
I hope its not too difficult for me to understand the explanation @way3edgyentertainment
Just don't understand why I'd do that
I'm sure you're right
@way3edgyentertainment try using
str.replace(/[^0-9a-z]/gi, '')
@TracesOfNuts you can also try doing this instead
forstr=str.replace(/[^0-9a-z]/gi, '').toLowerCase();
@TracesOfNuts thanks, that did it.

Hi @all
I'm stuck in "Sum All Numbers in a Range" problem here is my code
var numInRange = 0;
var numOfRange = 0;
var accuStatus;
function sumAll(arr) {
var maxNum = Math.max.apply(null, arr), minNum = Math.min.apply(null, arr);
for(var i = minNum + 1; i < maxNum; i++){
numInRange += i;
}
arr.reduce(function(accumulator, currentValue, currentindex, array){
numOfRange = accumulator + currentValue;
});
return numInRange + numOfRange;
}
sumAll([5, 9]);
result is coming correct but don't know it's not passing this solution
@sainiabhi try putting all the var in the function
@sainiabhi
@sainiabhi unction sumAll(arr) {
var x=Math.max(arr[0] ,arr[1]);
var y=Math.min(arr[0] ,arr[1]);
var temp=0;
for(var i=y;i<=x;i++)
{
temp=temp+i;
} return (temp);
}
sumAll([1, 4]);
Hi everyone, In this exercise https://www.freecodecamp.com/challenges/return-largest-numbers-in-arrays I tried using the spread method
@TracesOfNuts i can't do that as numInRange will throw 0 always if ideclare them in function
@adityavisen thanks for sharing the solution but can you please tell the problem in my code

@carpben
@johnnunns Still stuck?
@sainiabhi glad to help! technically what you're doing is also correct. it's just that FCC checks everything in the function
@TracesOfNuts
function sumAll(arr) {
var numInRange = 0;
var maxNum = Math.max.apply(null, arr), minNum = Math.min.apply(null, arr);
for(var i = minNum; i <= maxNum; i++){
numInRange += i;
}
return numInRange;
}
sumAll([5, 9]);
had to do some looking at the record collection I did a while back. Now I'm just figuring out breaking the other statements away from the for loop
@revisualize
@johnnunns NO!

@carpben hi can you share your code?
Here it is:
function largestOfFour(arr) {
// You can do this!
var maxNum;
for(i=0; i<i.length(); i++)
manNum = Math.max(...arr[i]);
return maxNum;
}
largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]);
@johnnunns Umm.. Put your No such property back inside of your for loop.
with akira likes
when it's inside the for loop it only tests right on the first contact
@johnnunns else does not take a condition remove the condtion and move that else part inside loop to connect it with first if
@johnnunns show me your code. (JUST THE FUNCTION!)
@johnnunns You do NOT need to continue pasting the contacts array. We don't want to see it.
*yawn*
@carpben hmm maybe its the
...how bout trying
manNum = Math.max(arr[i]);
@revisualize sorry for spamming with contacts. But you can read my code inside where it guides you to write the code
hello, i don't understand an exercise and i have no idea how to solve it
it's this one : var myStr = "FirstLine\n\SecondLine\r\Third Line";
@revisualize I'm actually not enjoying your help anymore, thanks anyways bud. I'll figure it out myself
johnnunns sends brownie points to @revisualize :sparkles: :thumbsup: :sparkles:
:star2: 2844 | @revisualize |http://www.freecodecamp.com/revisualize
@grandmasterundead which one ?
@grandmasterundead Third Line is not the same as ThirdLine
escape sequences
Assign the following three lines of text into the single variable myStr using escape sequences.
FirstLine
\SecondLine\
ThirdLine
but i do not know how to do that
everything i;ve tried, in vain
@grandmasterundead Third Line is not the same as ThirdLine
@TracesOfNuts This won't work as the max function needs to receive number parameters and not an array. I thought the ... somehow breaks it into the elements. That's what it should, but I might misunderstood the syntax.
@grandmasterundead backslash should be before
\r not after to it
How to use escaped double quotes (\"). ?
yes but now i have to do that three lines into myVar
@johnnunns Here you go. Gist by revisualize / FreeCodeCamp - Profile Lookup.js
var myStr; // Change this line
I am a "double quoted" string inside "double quotes".
the next one
var myStr = "FirstLine\nSecondLin\rThirdLine";
i've tried everything and i do not know how to do that
@grandmasterundead need
\\ before and after SecondLine
Can someone help me understand how I can use a closure in my use case?
@grandmasterundead SecondLin is not the same as SecondLine
not yet
@carpben ah i see where's the problem. hmm.
Math.max uses numbers as arguments but you're using array instead
yes but the ... should spread the elements of the array.
It does.
FCC gives you a warning.
It doesn't give you an ERROR
Just a warning.
@revisualize aye, thanks, seems that i deleted a lot trying to make it work hehe :D @ghulamshabir it was confusing because I thought I had tot make them on three lines and in console it didn't show them on three lines.

@grandmasterundead :smile:
:D
@revisualize and am I using the operator correctly? Why doesn't it work?
It does work.
Your other logic isn't correct.

"rose",
"tulip",

// Only change code below this line
var secondTree = myPlants[1].list["1"]; // Change this line
@mattcharlesh You're trying to access an array element with a string.
Quotes define strings.
@carpben ah. I'm not familiar with the ... syntax. this is what I did instead.
function largestOfFour(arr) {
var i,j,newArr=[];
newArr.length = arr.length;
for (i = 0; i<arr.length; i++) {
newArr[i] = 0;
for (j = 0; j<arr[i].length; j++) {
if (arr[i][j]>newArr[i]) {
newArr[i]=arr[i][j];
}
}
}
return newArr;
}

@carpben Based on this code here: :point_up: January 4, 2017 10:12 PM Your issue is..
return statements cause functions to halt and return. If you're trying to do a return inside of a loop it will cause the function to halt and return the information that you specify.
@carpben share me your code if you managed to use the
Math.max for that problem
So, if your loop has a return statement inside of it.. It doesn't really loop.
Unless of course that return is inside of another conditional block.
@TracesOfNuts I have 3
@TracesOfNuts In your code:
newArr.length = arr.length; doesn't do anything.
I don't think.
Maybe it does.
@revisualize yea. i think its redundant
@revisualize thanks for highlighting!
tracesofnuts sends brownie points to @revisualize :sparkles: :thumbsup: :sparkles:
:star2: 2847 | @revisualize |http://www.freecodecamp.com/revisualize
@TracesOfNuts are you relative a newbie like me?
I'm going to solve that one again. I have an idea.
@TracesOfNuts your code is not efficient, you have unnecessary code
newArr.length = arr.length; and newArr[i] = 0; you could have used a variable say var largest=0;
@carpben most of us are i suppose ^^
@TracesOfNuts cool. Please be aware that your comparison will not necessarily return the max number, but might return a 0 instead.
@TracesOfNuts I just made another solution using the spread operator.
@ghulamshabir yup. i though i needed to declare the length of the array
thought*
@revisualize If you know the spread operator can you please refer to my question as well.
@TracesOfNuts array length expands and shrinks by itself when you use push/shift and arr[i]=...
@carpben I'm sorry what question?
@TracesOfNuts cool. Please be aware that your comparison will not necessarily return the max number, but might return a 0 instead.
yup this is with assumption that the array consists of only positive integers.
how do make var a=b
@official4code How do you assign the value of 7 to a variable
Now if you want you can use a variable to store values.
Like in mathmatics.
So, you can do several things with variables. But, you need to understand that variables hold values and variables can be used with other variables.
So, how do you assign the value of 5 to a variable
How do you assign the value of
Look at the way things are written.
How do you assign the value of 42 to a variable
Variables hold values. Just understand that.
num? ... var num = 7;Now if you want you can use a variable to store values.
Like in mathmatics.
num + 3 = 10 What is the value of num?var x = num + 3; ... That outputs 10So, you can do several things with variables. But, you need to understand that variables hold values and variables can be used with other variables.
So, how do you assign the value of 5 to a variable
x? ... x = 5; (Which is also overwriting the previous value of 10 from above.How do you assign the value of

pls share it
@TracesOfNuts I just made another solution using the spread operator.
But, @carpben hasn't solved it yet.
@revisualize I posted it here 10-15 minutes ago, and after not receving an answer I posted it in this thread: https://forum.freecodecamp.com/t/spread-operator/72770

@ghulamshabir my solutions work. jsut trying to see if there are variations to solving the problem using different methods that im not aware of.
@carpben Yes here.
@TracesOfNuts yes i know your solution works, but it will not hurt if you try to do it again with different methods
@amarg26 setGear should take a parameter and assign that to gear and getGear should just return gear. finally gear should be initialized with 0 not with 1

@amarg26 I said setGear should take a parameter and assign that to gear
space infront of string inside @jainishpanchal
@revisualize but what about the message I get "Spread/rest operator is only available is es6"?
@amarg26 setGear should take a parameter and assign that to gear and getGear should just return gear. finally gear should be initialized with 0 not with 1

which is there is the map
Can someone tell me a good way to debug the code on in the editor. i want to step through loops and watch what is happening?
"a should be assigned to b with ="(i still don't get, how do you do this).
@Unlawfulspoon just increment/decrement count in the switch depending on card's value then after the switch check if count value is higher than zero return count plush Bet otherwise count plus Hold

Remove all the backslashes ()
You should have two single quotes ' and four double quotes "
Only remove the backslashes \ used to escape quotes.

@amarg26 setGear should take a parameter for example like this

@hope4 just copy the object above and change names and i.e.

@ghulamshabir ok
I can't understand this. For some reason I use a simple console.log(i) sentence, and it doesn't show in the console.
@ghulamshabir not working
?
@jainishpanchal post the code

@hope4 you should have two objects in the array like this
[{...}, {...}]
@hope4 add a comma after first object
thanq @ghulamshabir , @MaeStat
@hope4 yes, @ghulamshabir is rihgt
@donswavey you have not added anything to the code. anyway you are supposed to add
item to the end of arr then remove and return first element. you will need two array methods. previous lessons titles Manipulating Arrays with... might be helpful
for (var i = 0; i < arr.length; i++) {
for (var j = 0; j < arr[i].length; j++) {

@rahul-thakoor did you try without last " else if"? Just only "return..."?
myVar = myVar should be changed
Use the ++ operator(how is it done)

@official4code
var num = 5;
num = num + 1; // 6
num += 1; // 7
num++; // 8See how the one for getting num from 7 to 8 doesn't use the assignment operator (=)?
@MaeStat thx

i will try it out
@MaeStat can you explain why my original code does not work?
function chunkArrayInGroups(arr, size) {
// Break it up.
var newArr = [];
for(var i = 0; i < arr.length; i += size) {
newArr.push(arr.slice(0, size));
console.log(newArr);
arr = arr.slice(size, -1);
console.log(arr);
}
return arr;
}
chunkArrayInGroups([0, 1, 2, 3, 4, 5, 6, 7, 8], 4);
hi guys
i needsome help with chunky monkey
my array shrinks every itteration
but on the last one i have only 1 element left in array so slice doesn't count him in
@rahul-thakoor may be last return breake out your for loop
arr = arr.slice(size, -1); is reducing your array
@rahul-thakoor and inerations over loop stoped
@ghulamshabir yeah but when i need to put just the last (element in this case 8) because beggining should be at 4
i mean it doesnt make an 8 into that last array it should go through
@sennator2 all you need is this line
newArr.push(arr.slice(0, size)); just adjust the slice arguments to get you right chunks of the array
Hey, can you help me out with this code: var myStr= "Firstline"\n \"SecondLine"\ \r"ThirdLine";
I'm supposed to make it look like:
FirstLine
\SecondLine\
ThirdLine
@Dhwani24 remove spaces and quotes inside the string and Line with caps L in Firstline
@ghulamshabir
var myStr= FirstLine \n \ SecondLine \ \r ThirdLine;
or
FirstLine\n\SecondLin\\rThirdLine;
It still doesn't work
Error Statement: myStr should have encoded text with the proper escape sequences and no spacing.
you still have spaces in it
@ghulamshabir Yeah, thanks :)

@ghulamshabir sorry but can you explain me this a bit
newArr.push(arr.slice(0, size));
i have to start at 0
and end with size
@sennator2 no
@ghulamshabir no?
just think about size if size is 2 then you chunks of array of lengths 2. means first chunk with first two and second with third and fourth and so on
hi everyone, I want to add hashmap table from an array to an hash table object

@jmbravo it worked
@nhanly91 as you have used keys in quotes like '1' , so the solution might not work, try removing quotes around the keys in inputHash
@Cafam you can't do b = a because "a" doesn't have value
Fix the function isLess to remove the if/else statements.
function isLess(a, b) {
// Fix this code
if (a < b) {
return true;
} else {
return false;
}
}
// Fix this code
if (a < b) {
return true;
} else {
return false;
}
}
Any help, please? https://www.freecodecamp.com/challenges/stand-in-line
how to fix this
@jmbravo ok
@rameezh remove all if-else structure just keep first return and the condtion of if
function nextInLine(arr, item) {
// Your code here
return item; // Change this line
}
// Test Setup
var testArr = [1,2,3,4,5];
// Display Code
console.log("Before: " + JSON.stringify(testArr));
console.log(nextInLine(testArr, 6)); // Modify this line to test
console.log("After: " + JSON.stringify(testArr));
@jmbravo // Example
var ourVar = 19;
// Only change code below this line
var myVar = 9;
what do you need?
@jmbravo you are supposed add
item to the end of arr them remove and return first element. you will need two array methods for this. the previous lessons titled Manipulating Arrays with... might be helpful
@jmbravo Define a variable a with var and initialize it to a value of 9.
That's ok, isn't it? @Cafam
no
could you please paste all the exercise?
@ghulamshabir thank you! I'll check it

@jmbravo Initializing Variables with the Assignment Operator
It is common to initialize a variable to an initial value in the same line as it is declared.
var myVar = 0;
Creates a new variable called myVar and assigns it an initial value of 0.
Instructions
Define a variable a with var and initialize it to a value of 9.
@Cafam yes very common
// Only change code below this line
var a = 9;
@jmbravo ok
@Cafam they say "var a"
your code was good but you named the variable wrong @Cafam
hello guys
i'm having a trouble for reverse a string section
@mahdiarn what you have ?
i'm doing it using for loop ways, i want to know how to do it using prototype reverse way
@ghulamshabir i'm using this code :
function reverseString(str) {
var tes = "";
for (var i=str.length-1;i>=0;i--) {
tes += str[i];
}
return tes;
}
reverseString("hello");
can you help me how to solve it using split, join, and reverse?
hey guys.. some issues with my Wiki viewer. 1) i want to get it remove the previous search each time a new search is started(will removing the class with javascript each time the search button is clicked help?).. 2) ive tried all the parameters given for the body/summary/extract/ to show but its still not working..

@mahdiarn is that code working ?
it's working
@ghulamshabir but i want to solve it how the instructions want
@ghulamshabir by turning the string into an array then reverse it
@mahdiarn do it as you've said it
@ghulamshabir good morning bro
@ghulamshabir good morning bro
@Lumexralph the problem is how to split a string into an arrays?
@mahdiarn the loop version is good to learn how loops can be used, if you want to do it using Array.prototype.reverse then convert the str to an array then reverse it then join it back to string
@Lumexralph good after noon
@mahdiarn str.split("") will return an array
@ghulamshabir okay it works, thanks for the help mr ghulam

@Daahel remove \" you don't need them you only need
\\ for a backslash
@egbuna try .html instead of .append
@Daahel remove double quotes
"" you need \n \\ \r \\ before and after SecondLine

```var Bike = function() {
var gear =0;
this.getGear = function() {
return gear;
};
function setGear(gear) {
var g1= gear;
}
};
var myCar = new Car();
var myBike = new Bike();
myBike.getGear();
g1=myBike.setGear(gear);
```
TypeError:myBike .setGear is not a function
@amarg26 because you didn't make it public to any instance of Bike... use
this.setGear
@amarg26 use g1 as setGear parameter and assign to gear like this gear = g1
Modify the function abTest so that if a or b are less than 0 the function will immediately exit with a value of undefined.
how to do this
@ghulamshabir i only get one(1) result using .html
@rameezh you need to simplify that if-else structure so you only return the condition what is in the if
@rameezh use if control statement to check if a or b < 0, then return or return undefined anyone will work
if(a<0 && b<0){
return undefined;
}
return undefined;
}
@rameezh no, use ||
i use this statement but its now working
please fix this
```var Bike = function() {
var gear =0;
this.getGear = function() {
return gear;
};
this.setGear = function() {
var g1= gear;
};
};
var myCar = new Car();
var myBike = new Bike();
myBike.getGear();
g1=myBike.setGear(gear);```
@armarg26
this.setgear doesn't have a parameter to set to gear
@egbuna oh i see, then you can use append. but before using .append set the elements to an empty string like this. .html("")
@egbuna still have any problems?
like this
this.setGear = function(gear) {
var g1= gear;
};
@Lumexralph
@amarg26 yeah, but set gear in Bike to gear parameter....or use another name for the parameter for unambiguity
@ghulamshabir i still get the same results as the first
@egbuna you sure you put the .html("") before .append ?
@darkflikk yes bro
@ghulamshabir yes i did
@egbuna so what do you need?
@amarg26 you're changing the value of
var gear to the parameter of this.setGear when it's called
@amarg26 this
{ var g1= gear; } should be { gear = parameter from the setGear method; }
@darkflikk some issues with my Wiki viewer. 1) i want to get it remove the previous search each time a new search is started(will removing the class with javascript each time the search button is clicked help?).. 2) ive tried all the parameters given for the body/summary/extract/ to show but its still not working..

regarding tictactoe game, how do i change the content of a box and make it unchangeable
@egbuna hmmm, looks strange

@Lumexralph thanks a lot for detailed explanation.

I can use .one("click") to make my symbol appear only once but the ai might overwrite it
@amarg26 :+1:
@egbuna you have a strange mix there, you should start to organize your code better
function mutation(arr) {
var firstWord = arr[0].toLowerCase();
var secondWord = arr[1].toLowerCase();
for ( var i = 0; i < secondWord.length; i++ ){
if (firstWord.indexOf(secondWord[i]) >= 0){
return true;
}
else return false;
}
}
mutation(["Alien", "line"]);
question
my if statement checks to first true
and then returns
@egbuna you should start with the ajax request and put all the parameters in your data object so one can see what parameters you send in the request
how can i make it check every result
@sennator2 this will assume that if the first letter matches then the entire string is matched that's wrong
@sennator2 your if statement will not finish the loop before it returns
@Lumexralph i know that
how to change that
@ghulamshabir yup :D
@sennator2 if (firstWord.indexOf(secondWord[i]) >= 0){
return true;
} this is wrong
return true;
} this is wrong
thought i did better this time :worried: @darkflikk
@egbuna it takes time, you can do it
@sennator2 think opposite of it. if first letter/any letter does not match then it's assumed that string will not match
@ghulamshabir makes sense :)
