@crazymaster49 u need to create a math expression and assign it to a variable...
javascript will calculate whatever result is
javascript will calculate whatever result is
ie:
total = 2+5;
ok thank you all, but how do you use finding a remainder in JavaScript? if that is not correct.
+ adition operator total = 2 + 5/ division operator total = 2 / 5* multiplication operator... total = 2 * 5soo.. how u would find remanding using the remainder operator ???
%
Can you give me an example @moigithub in code of how this is used?
3 % 9 === 0
is it bad that i'm using google to figure out some codes/functions so i can use them in the algorithm challenges? or is that normal to do...?
@Symbolistic not at all
re-read above.. the examples using differents operators.. @crazymaster49
@Symbolistic knowing how to google is the sign of a good programmer lol
@hippybear cool, I was wondering cause it felt really easy after googling my problems, lol.
@crazymaster49 you can also do this in your devtools and see it in action
of course u need to use whatever variable name /values the instruction tells u to do.. @crazymaster49
that thing had me baffled for a bit
@hippybear Seems like you're right about remainder vs modulo https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators#Remainder_()
?
@moigithub Thanks i am still working on figuring this out.

@Egoscio right??
A strange step from python to %
"the difference being that the modulo operator result would take the sign of the divisor, not the dividend."
In Swift, they implemented the actual modulo function
and go
Have to do C and Java this coming semester
not too happy about that
I'm coming from 2 years of fullstack javascript experience to fullstack Swift
(Web and Node.JS => Swift iOS and Vapor server side)
Very neat transition
I love node
although there is some new issue where require wont work anymore so now you have to redo all your code
the import BS?
Does it really all go back to the dude who broke the internet in 17 lines of code?
Still not even fully implemented AFAIK, still requires transpiling via Babel and co
nah, that's something completely different
I need help with this exercise, Logical Order in If Else Statements
@hippybear How did a NPM dependency affect the ES6 module syntax?
that shits srs biz
IIRC in a couple of hours later, someone cloned the project and fixed the issue
one of the contributers
@hippybearfunction orderMyLogic(val) {
if (val < 10) {
return "Less than 10";
} else if (val < 5) {
return "Less than 5";
} else {
return "Greater than or equal to 10";
}
}
// Change this value to test
orderMyLogic(9);
order matters... @CageEcharte
(async ) code run from top to bottom... and only 1 of the if /elseif blocks gets executed
soo knowing that ....
if val is 4.. what if block gets executed ????

moigithub @moigithub wonder if @CageEcharte fell asleep :sleepy: :question:
this chunk array in groups is killing me lol
Im gonna get it though
@Egoscio Hey! one question going back to my problem. What does the ".apply(this, arguments)" mean? btw, your solution works! I just don't understand it lol
instead of doing someFunction(1, 2, 3)
you can do someFunction.apply(this, [1, 2, 3])
you can replace "this" with anything you want present as the function's this
can even be {}
In the function,
arguments is an array of arguments used to execute the function, you're just passing it on synthetically
(note: the
arguments array isn't really an array, so it doesn't conform to the standard Array protocol)
you will encounter it more in node
oops
Well, arguments is a wannabe array, it's an object with numbered properties
but it doesn't have stuff like
.reduce or forEach (IIRC)
an array of objs
arrays are robust
can someone give me the idea behind "Wherefore art thou" challenge Please
I didnt get there yet so I dunno
@brianrudloff
> var realArray = []
undefined

@Byzgig never heard of it
ATGC ? @Byzgig
u function get called with a string.. u need to return an array of array.. with their pair
u function get called with a string.. u need to return an array of array.. with their pair
@Egoscio well yeah but after you put in your args the array will be real no?
if string is "AA" u return [["A","T"],["A","T"]]
T is pair of A.. (check the instructions)
T is pair of A.. (check the instructions)
add backticks at start and end.. on its own line
function pairwise(arr, arg) {
var job = [];
var select = false;
var test = arr;
// console.log(test);
for(var i = 0; i < arr.length; i++){
select = false;
for(var j = 0; j < arr.length; j++){
if(arr[i] + arr[j] === arg){
job.push({one: arr.indexOf(arr[i]), two: arr.indexOf(arr[j])});
arr[i] = false;
arr[j] = false;
}
}
console.log(arr);
console.log(job);
}
//console.log(arr);
return job.reduce(function(a, b){
return a + b;
});
}
pairwise([1, 3, 2, 4], 4);
@hippybear An arguments "array" is something like:
var arguments = { 0: 'firstArg', 1: 'SecondArg' }
it's not
var arguments = ['firstArg', 'SecondArg']
function doStuff(a,arr){} doStuff(1, 44) will now have an array of ["44"]
@brianrudloff Also, here's a little example of
.apply():> function greeting(firstName, lastName) { console.log('Hello, ' + firstName + ' ' + lastName + '!') }
undefined
> greeting('John', 'Doe')
Hello, John Doe!
undefined
> greeting.apply({}, ['John', 'Doe'])
Hello, John Doe!
undefined
>
lol
youre amazing :)
Love the examples
A node REPL is sometimes the best way to demonstrate stuff.
I love the freenode rooms for the js repl

like this?
@Byzgig
soo u can just use i and j variables.. no indexOF needed
and... since ur 2 for loop using the same indice.. if u have this array [1,2,3]
and.. i and j are 0
u doing
u should NOT use the same element to make the sum calc
arr.indexOf(arr[i]) will return the same value of i .. also the other one.. will return j valuesoo u can just use i and j variables.. no indexOF needed

arr[0] + arr[0] --->>> if(arr[i] + arr[j] === arg){u should NOT use the same element to make the sum calc
function largestOfFour(arr) {
var finalarr = [];

is this what I am supposed to do? It's still outputting a empty array
@OmAgarwal2002 IF u gonna use math.max u only need 1 loop....
apply takes an array as argument
soo on that case.. u only need 1 loop to iterate the main array.. and "pick" the subarray
apply takes an array as argument
soo on that case.. u only need 1 loop to iterate the main array.. and "pick" the subarray
thats why i used one loop in the first place
for (var i = 0; i < arr.length; i++) {
for (var j = 0; j[i] < arr.length; j++) {
@OmAgarwal2002 still can't see any reference to arr in your code
@moigithub so my question is then, how do i not use the same element twice, and then how do i add only the smallest indexes of the array?
@OmAgarwal2002 the second arg in apply is array I c j[i] which = nothing
@OmAgarwal2002 soo if
and
numbers dont have indices.... and u should access the array element instead
j have a 0 valueand
i have also 0 value ur code doing 0[0] <---is that correct ??numbers dont have indices.... and u should access the array element instead
just use one loop and ref arr[i] instead of j[i] @OmAgarwal2002
@Byzgig whats the purpose of ur job variable??
(and.. if thats what i think it is... ) i used an array variable to keep all the used values.. so i dont reuse it again
probably thats what ur job variable doing too..
(and.. if thats what i think it is... ) i used an array variable to keep all the used values.. so i dont reuse it again

@moigithub job is just pushing the indexes to an array, to be added later
@moigithub yes, that is what i ma trying, and setting the value in the og array to false so it never equals the arg again
@Byzgig
if(arr[i] + arr[j] === arg && i!==j){ // compare if i is different than j.. so u not do arr[0] + arr[0]
job.push({one: i, two: j)});
@CageEcharte sry im not following ... can u repost ur code again plz ?
order matters... @CageEcharte
(async ) code run from top to bottom... and only 1 of the if /elseif blocks gets executed
soo knowing that ....
if val is 4.. what if block gets executed ????
@moigithubfunction orderMyLogic(val) {
if (val < 4) {
return "Less than 10";
} else if (val < 6) {
return "Less than 5";
} else {
return "Greater than or equal to 10";
}
}
// Change this value to test
orderMyLogic(7);
function orderMyLogic(val) {
if (val < 10) {
return "Less than 10"; // first block
} else if (val < 5) {
return "Less than 5"; // second block
} else {
return "Greater than or equal to 10"; // third block
}
}
// Change this value to test
orderMyLogic(9);
no.. u should NOT change ur numbers... that 4 was a test value.. to check ur code logic
soo u need to "execute" ur code mentally.. and evaluate ur if condition.. vs a value
orderMyLogic( 4 ); <--- i said.. IF val is 4.. what ur code will do ??
u have 3 blocks there
soo question was .. if val is 4.. which of those 3 blocks will get executed ?
first, second or third?
what u need to do .. is just replace val with 4.. and DO the comparation the condition is doing
if (val < 10) { --->>> if (4 < 10) { and ask ur self.. is 4 less than 10 ?? is true or false???if its true.. then u will know which block gets executed...
function orderMyLogic(val) { <--- THAT val.. ur argument variable namesoo when u execute/call ur function like this
orderMyLogic( 4 ); what do u think willl be the value of val

can someone tell me why i keep getting "TypeError" Cannot assign to read only property '0' of string "i'm".

}
str = newStr.join(' ');
return str;
}
titleCase("I'm a little tea pot");
@Byzgig since false+1 returns 1... u also need to check if arr[i] and j are not false so it skip it
i gotta make every 1st letter of each word capital
on Javascript strings are immutable @Symbolistic
soo u cant change part of...
u need to rebuild the whole string and reassign
(if u recall the myStr = "Jello world" exercise ) one of the very first u did

myStr[0] ="H" // fail
and makes things a bit more confusing
@Symbolistic Makes things less confusing. Imagine treating a string like an array you can modify at will!
That's why things like split('');
exist
and .join();
function titleCase(str) {
str = str.toLowerCase();
str = str.split(' ');
for(var i=0; i<str.length;i++){
str[i]=str[i].split('');
str[i][0] = str[i][0].toUpperCase();
str[i]=str[i].join('');
}
return str.join(' ');

such as if someone show up on in a place they either mark them preset or absent
they do that on their own phone or on a device at the place
that a lot for an attendance website and I can make two social media app like Instagram for that
You should hire someone from fiverr.com they can make 3 social media websites for 5 USD
The project you are describing requires a backend language as well (code that runs on a server, and interacts with a database)
So I am reading this code: http://codepen.io/dsgnrmdy/pen/qbjEGy ... and I do not understand why the author is using a script src="http...js"
*.org
Then you need a database to store your users. Mongodb is pretty popular on the node.js world, and it's easy to start with, plenty of documentation online
So now you have a clientside, backend, and database all powered by Javascript, awesome right?
Well, I'm not familiar with templates, if that's the path you choose to take.

Hi guys... Can aanyone help me with switch statement?
@Chrono79 here is my code ````

// Only change code below this line
val = 1;
console.log("alpha");
break;
// Only change code above this line
return answer;
}
// Change this value to test
caseInSwitch(1);

the message I get is unexpected break....
@orionishere look at the pseudocode example:
switch (num) {
case value1:
statement1;
break;
case value2:
statement2;
break;
...
case valueN:
statementN;
break;
}
you have to use the same structure
Also read mdn page for more examples and longer explanation: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/switch

collection[id][prop] = value;
}else{

}
}

I went through it.... I have more doubts now.... @Chrono79
@THalletProtech that's wrong, you have to delete the property if value is empty string
function wordBlanks(myNoun, myAdjective, myVerb, myAdverb) {
var result = "";
// Your code below this line
// Your code above this line

switch (val) {
case 1:
console.log("alpha");
break;
}
// Only change code above this line
return answer;
}
// Change this value to test
caseInSwitch(1);
@orionishere that's almost ok (but incomplete), you have to change answer value instead of using console.log, add the other cases too
I just wanted to check first with one case... so I just put in code for one case... However I've tried with full code.... not working.... @Chrono79
@nicopcat the exercise is asking for a sentence to be built using the 4 word types given. it may be easiest to begin by making a complete (spacing & punctuation) sentence, using the 4 words. to make sense, the complete sentence will require a few "filler" words. :sparkles:

Hi all, I'm struggling to wrap my brain around introducing a Twitter widget to my quote generator. I could use a hand if anyone's available.
My work so far: https://codepen.io/SaxManMike/pen/jAgrEx
i'm stuck on the Seek and Destroy challenge. I looked at all the references on MDN, w3schools , and tutorialspoint.com. can someone give me a hint?
```javascript function destroyer(element, index, array) {
return (element != arguments[1]);
}
var filtered = array.filter(destroyer);
destroyer([1, 2, 3, 1, 2, 3], 2, 3);
```
@mejorna I am sorry, I am stuck on that one too. I don't understand the whole arguments functions back-and-forth. :(
@SaxManMike the url 'http://twitter.com/share?' plus whatever text.
@mejorna destroyer is a function,how coud you make it as a argument
Once you've got the quote text, you can set the html attribute of the button to the twitter share url, appending the quote text after the question mark.

@SaxManMike si. When I did mine, I removed the twitter share button each time the new quote was generated. Then, when the new quote was appended, a new twitter button with the quote text was appended back
one thing , for dynamically-added buttons , you need to use $(document).on('click', '#buttonid', function(){}); instead of $('#buttonid').click(); ... remember that if poss.
Something about how the dom won't recognize it immediately .. it's just something I found out once after almost crying about a proj.
sorry, I meant $(document).on('click', '#buttonid', function(){...}); instead of $('#buttonid').click(function(){...});
var a = 3;
var b = 17;
var c = 12;
// Only modify code below this line
a += a + 12 ;
b += 9 + b ;
c += c + 7 ;
whats wrong with my code please help.
Compound Assignment With Augmented Addition
Same with all variables to the right, you don't need them with the +=
Nope, sorry, that's wrong...I'm tired :P
@tbushman This is what I wrote, it doesn't quite seem to work...
$(document).on('click','#tweet', function(inspiration){
$("#tweet").attr("href", 'https://twitter.com/intent/tweet?hashtags=inspired&text=' + inspiration);
});
$("#tweet").attr("href", 'https://twitter.com/intent/tweet?hashtags=inspired&text=' + inspiration);
});
Inspiration is the variable with the quote
or you could do window. (load?) something-or-other. I'd have to look that up
Hello Does anyone use React? I can't figure out its behaviour...
I use React to trigger Bootstrap modal --> include some input field
The problem is whenever I click on those input field, I cannot scroll anywhere anymore...
I use React to trigger Bootstrap modal --> include some input field
The problem is whenever I click on those input field, I cannot scroll anywhere anymore...
any idea?
Oooooo, so close! It isn't passing my variable for some reason
It says "[object Object]"
Is that because my inspiration variable is private as part of the quote function?
function quoteText () {
var num = Math.floor( Math.random() * quotes.length);
inspiration = quotes[num];
return inspiration;
}
var num = Math.floor( Math.random() * quotes.length);
inspiration = quotes[num];
return inspiration;
}

Hello. I'm stuck on item #5 of the Profile Lookup challenge. What am I doing wrong? ```for (var i=0; i < contacts.length; i++) {
if (contacts[i].firstName == firstName)
if ( contacts[i][prop] )
return contacts[i][prop];
} //items #1-#3 work
{ return "No such contact"; } //item #4 works
if (contacts[i].hasOwnProperty(prop) === false )
return "No such property";
@SaxManMike you're missing the last part of the math.random deal
Math.floor(Math.random() * (max - min)) + min;
so your num var is out of range
maybe

@Natto278 on the last if statement, the '===false' cancels out the .hasOwnProperty() statement, I think
so it becomes if (false === false)
@tbushman Isn't the min 0, so when you simplify the equation you get what I had?
I was just guessing and haven't looked too closely , sorry
@tbushman So I need to rewrite that last if statement. Also, I think I messed up posting my code using markup. I know it's ``` <shift><enter> Paste your code <shift><enter>. But I get the last couple of commands messed up. What am I doing wrong?
so do
shift enter
then add
then shift entershift-enter gives line breaks between ```s
so if you did those ticks, then shift-entered, then pasted code, then shift entered again, and added closing ticks, ... it's a recurring issue on here. One poor man earlier almost pulled his hair out explaining

@tbushman I rewrote my code but it's still not working. ```for (var i=0; i < contacts.length; i++) {

{

return "No such property";
}
```
help format
@hacu9 use three `s to outline your code.
@Natto278 I was going to say, if you remove the '===false', then the statement has the reverse meaning and you'd need to switch the content between {}s
@tbushman Would you be willing to take a look at my JS and see why the variable isn't passing to the Tweet?
@tbushman Are you saying that for then first post of my code today?
@Natto278 I would write 'if (contacts[i][prop] == 'null')' ...try that or == 'undefined' ... use console.log() to test
I need M to be lowercase
@Natto278 I'm not sure what post ?
@tbushman Thanks for all your help, this has been very instructive! I appreciate you not spoon feeding me the answer

@tbushman I tried both of your suggestions, but it's still not working.
for (var i=0; i < contacts.length; i++) {
if (contacts[i].firstName == firstName)
if ( contacts[i][prop] )
return contacts[i][prop];

var lowCase = str.toLowerCase();
var result = lowCase.replace((/\b\w/g), function(l){

}
@SaxManMike you're trying to append a function to $('#quoteMe') ... when quoteText could be a variable insteat of a function
function titleCase(str) {
var str1=str.split(" ");
var str2=str1.map(function(val){
return val.toLowerCase().replace(/\w/,val.charAt(0).toUpperCase());
});
return str2.join(" ");
}
var str1=str.split(" ");
var str2=str1.map(function(val){
return val.toLowerCase().replace(/\w/,val.charAt(0).toUpperCase());
});
return str2.join(" ");
}
@SaxManMike see what I mean? Just put var inspiration in your div instead of quoteText, and remove the quoteText function, is what I would try
@hacu9 you can just do
lowCase.replace(..).toUpperCase();I think
I think I see what you mean, I just need to figure out the syntax

@Natto278 ... but I haven't worked on that exercise and I just had a similar issue with an if statement yesterday... kind of guessing. sorry
@hacu9 right. I remember having the same issue, but I can't remember which exercise. Which is it called?
i think i just need to add something to the regex
Well, I got the code working more cleanly, but the Tweeting still isn't working
@hacu9 oh ok. Then you were on the right track. I am sorry. One moment. It's something about adding parentheses to the regexp
@hacu9 sorry. I was wrong. Go back to how you had it because you need the function as a replacer for the regex. Do that first. Accept my apologies. :P
@tbushman its alright,thanks i appreciate help :P i just cant figure out how to ignore the '
@hacu9 Yeah, I'm looking at my soln and I replaced the " ' " with an underscore, then replaced the underscore with " ' " at the end. Totally hack-y.
@tbushman I fixed the JS code so you don't have to scroll for a thousand years to get to the code I'm working on
@SaxManMike maybe try removing 'inspiration' from function(inspiration) ? Did I mention I was an art major ? I'm not sure :P All guesses tonight.
@tbushman haha! Well, looks like I'm stuck for tonight then. I was a music major and there's no way I'm wrapping my brain around this tonight
I'm starting to chat like CamperBot, which means I should retire. Best wishes y'all.

@Natto278 and this two, you can just do an if else instead
if ( contacts[i][prop] )
return contacts[i][prop];
}if (contacts[i][prop] === false) // THis , if 'null', reads 'if (null === false)'
return "No such property";
}since you are testing if the property exist. if it does return the value from the lookup else return No such property
if contact in the ith index hasOwnProperty prop
//return value from the lookup
else
//return "No such property"js
var myStr="Here is a backslash: \\.\n\t\tHere is a new line with two tabs.";
js var myStr="Here is a backslash:\\.\n\t\tHere is a new line with two tabs.";

@Sohan2infoSec hint! which array method did you use in the previous challenges that added an item in an array?
@Sohan2infoSec here is the docs for Array, you can searh for methods that will fullfill those requirements from the challenge
Array
Array
@Sohan2infoSec another thing do not declare a variable same name as your function arguments
function nextInLine(arr,item){
var arr = [1,2]; //<-----------that has the same name as you function argument arr(will overwrite and cause confusion)
return item;
}
function caseInSwitch(val) {
var answer = "";

switch (val) {

case "delta" :
return answer;
break;
}
// Only change code above this line
return answer;
}
// Change this value to test
caseInSwitch(1);
what is the error
@kunal47 no return statement inside the switch, just assign the value to answer variable
@kunal47 another thing your case should be numbers, example
case 1 : ....(value of answer should be "alpha")
case 1 : ....(value of answer should be "alpha")
hi guys, I have a problem making a mouseover animation. it works the way I want, but it's very clippy. here's my code:
for(var j = 0; j < boxes.length; j++){
var interval;
var outInterval;
boxes[j].addEventListener('mouseover',function(){
var percent = -0.005;
var t = this;
clearInterval(outInterval);
interval = setInterval(function(){
t.style.background = shadeColor(boxColor, percent);
if(percent >= -0.1){
percent -= 0.005;
}
}, 10);
});
boxes[j].addEventListener('mouseout',function(){
var percent = -0.1;
var t = this;
clearInterval(interval);
outInterval = setInterval(function(){
t.style.background = shadeColor(boxColor, percent);
if(percent <= 0){
percent += 0.005;
}
}, 10);
this.style.background = boxColor;
});
}
by "clippy" I mean whenever you move the mouse, it runs the mouseOut function

@jamesmillerho
@jamesmillerho : I've made a few changes to your button. Take a look.
one thing I did is that I contextualized your styles. and removed the button positioning from the button.
This way, you can give this css to anyone and they can just plug and play
It's a good practice while developing frameworks/library that you delegate the positioning responsibility to the users/consumers :D

But I don’t know what to do next. @Egoscio

check /FreeCodeCamp chat
@Sohan2infoSec yeah, you need to return the value that is removed
@marhyorh I can’t figure it out :|.
@Sohan2infoSec There are two array methods that do those two things asked. Use them on

"function should then return the element that was removed.” How can I return it?

@Masd925 So it will Return the first value and then it removes the first number, right? Like doing from the outside to inside of the code.
Can anyone help with the above? I kind of need a hint so I can be distracted by coding instead of thinking about this girl...
@Sohan2infoSec
return arr.shift(); mutates the array by removing the first element and the method returns it. Then return keyword returns that removed element from the function.
``` var newstr;if(str.length>num){
newstr = str.slice(0,num-3);
newstr+=("...");
console.log(newstr,str.length);
return newstr;}else if (num>=str.length){
return str;
}else if(str.length<=3) {
var num1= num;
newstr = str.slice(0,num1-3);
newstr +=("...");
console.log(num1,newstr,str.length);
return newstr;
} ```
@Masd925 Yeah, but what is the relation of that with the topic “queue” of the lesson?
What does this requirement mean?
@Sohan2infoSec It tests whether the function does what it should.
Hi,I'm stuck on the Profile Lookup,as I don't understand the whats up with my if statement
function lookUpProfile(firstName, prop){
for (var i = 0;i < contacts.length;++i) {
if (contacts[i][firstName] == firstName && contacts[i][prop] == prop)
return contacts[i][prop];
}
}I've already tried multiple tests but no matter what I can't seem to compare those two strings. I know that by using '===' both type and value have to be equal but with '==' this rule shouldn't apply
this is just a portion of the code
@shxdow
contacts[i][firstName] <- quotes needed on firstName here
@shxdow Property existence check should be made with .hasOwnProperty() or .propertyIsEnumerable()
@Masd925 .hasOwnProperty only allows me to check the existance,not the value
@shxdow The simplest structure is two nested if's for the two checks.
@shxdow Yes, you access the value on if block. The test uses .hasOwnProperty()
@Masd925 oh,you're right. By using .hasOwnProperty iterating through the whole array is no longer necessary
// Setup
var testString = "Ada Lovelace and Charles Babbage designed the first computer and the software that would have run on it.";

// Only change code below this line.
var expression = /and./gi; // Change this Line
// Only change code above this line
// This code counts the matches of expression in testString

Hey peeps, this is supposed to output
FREE LOVE? (by moving the character selection 13 places), my output is DxRExEx >xOVEx? (the x's there to check which if/else chain it goes down - which I don't get because it works for the E's (R's in the input), but not the S or the Y. Anyway, here's the code if anyone can give me a hint?function rot13(str) {
var rot13 = "";
console.log('ABZ'.charCodeAt(2));
for (var i = 0; i < str.length; i++){
if (90 >= str.charCodeAt(i) && str.charCodeAt(i) >= 65){
if (str.charCodeAt(i) < 78){
rot13 += String.fromCharCode(str.charCodeAt(i)+13);
} else {
var num = 90 - str.charCodeAt(i);
rot13 += String.fromCharCode(61+num) + "x";
}
} else {
rot13 += str[i];
}
}
return rot13;
}
// Change the inputs below to test
rot13("SERR YBIR?");
@Masd925 what's the point in checking whether the property exists or not,the problem only cares whether values do so or not.
@shxdow The last requirement deals with contact not having property key stored in
prop.
@Masd925 but why I typed
arr.shift();
return arr.shift();
it results the same as
return arr.shift();
arr.shift();
return arr.shift();
it results the same as
return arr.shift();
Are they really equal to each other?
@Sohan2infoSec No it doesn't pass. Some problem with the page most probably.

@Masd925 I read the online doc for .hasOwnProperty but I cant tell whether it works even with arrays containing objects or not. Do I have to iterate throught every element in the array in order to know whether the property is there or not
@shxdow You iterate the contacts array and inside the loop block you have one contact contacts[i]. Then you should have two nested if's that test whether the contact is the one you seek (correct first name) and whether the contact has the property key stored in
prop. Simple .hasOwnProperty() test on the object is enough.
@letorruella I got rushed by a swarm of mosquitoes, it wasn't pleasant :|
this is my code function palindrome(str) {
// Good luck!
var liman = str.replace(/[^A-Za-z0-9]/g, '');
if (liman === liman.split('').reverse().join('')) {
return true;
}
else return false;
}
palindrome("eye");
Where am i wrong please
@shxdow contacts[i][firstName] <- quotes needed on firstName here
@Masd925 why are quotes needed
@Masd925 I'm sorry to bother you again but I can't seem to get it right
for (var i = 0;i < contacts.length;++i) {
if (contacts[i].hasOwnProperty(firstName) && contacts[i].hasOwnProperty(prop)) {
if (contacts[i][firstName] == firstName && contacts[i][prop] == prop)
return contacts[i][prop];
}
}
@shxdow You need to get the value of property key
"firstName". Nothing to do with the value of function parameterfirstName that would be used on the code your posted there contacts[i][firstName]
@shxdow The first if should only have the first name check, and the second the property existence check. Then only the returns on correct spots.
contacts[i]["firstName"] === firstName on the first and contacts[i].hasOwnProperty(prop) on the second if.
please
function golfScore(par, strokes) {
// Only change code below this line
return "Change Me";
// Only change code above this line
}
// Change these values to test
golfScore(5, 4);
condition
golfScore(4, 1) should return "Hole-in-one!"
golfScore(4, 2) should return "Eagle"
golfScore(4, 2) should return "Eagle"
ah ok you're starting out. One moment I have to look at the challenge
ok

@nidsnitesh ok it seems you can make some if statements but you should also make a calculation to see which string to return
Hey guys I am trying out the escape sequences in strings but it’s not working
var myStr = 'FirstLine\n SecondLine\\ ThirdLine\r’
var myStr = 'FirstLine\n SecondLine\\ ThirdLine\r’
Not sure I am doing this correctly
@nidsnitesh the first could be something like: if (strokes === 1){ return "Hole-in-one!"}
@pinglinh FirstLine newline backslash SecondLine backslash carriage-return ThirdLine <-- you have newline but after there should be a backslash. After SecondLine you put backslash, good, but then carriage-return is needed. You put the carriage returna after ThirdLine it should be before
the output should look like that I think
@pinglinh no spaces - and backslash is escpaed by a second backslash - see the table
nearly working
@sjames1958gm OMG thank you!!!!!!!!!!!!

Help me with Word Blanks pls
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("cat", "little", "hit", "slowly");
no wiki entry for:
me with word blanks plsfunction wordblanksmynoun 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 functionwordblankscat little hit slowly
I'm on the Convert Celsius to Fahrenheit, and am unable to pass it for some unknown reason. I tried fahrenheit = (celsius *9/5) + 32. Why is this wrong?
@txsrangers coz you are multiplying celsius by 9/5 and adding 32 to get the conversion in fahrenheit
true, but I wouldn't think the parenthesis would cause a problem.
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("cat", "little", "hit", "slowly");
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("cat", "little", "hit", "slowly");
Whats wrong with this
(not the first line)
Actually, the parenthesis were fine. I was spelling fahrenheit wrong. lol.
thanks for the help
@BlueExe yeah I was just following the order at which the question was worded
wordBlanks("dog", "big", "ran", "quickly") should contain all of the passed in words separated by non-word characters (and any additional words in your madlib).
wordBlanks("cat", "little", "hit", "slowly") should contain all of the passed in words separated by non-word characters (and any additional words in your madlib).
error on that 2
@BlueExe Your output
"catlittlehitslowly" from the function is not a sensible sentence.
You need some spaces and filler words and perhaps a full stop at the end.
I tried with
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("cat,", " little,", " hit,", " slowly.");
but doesnt work
@BlueExe
"A large "+myNoun+" ate my dinner." In that fassion.
@BlueExe A function call passes some words that are stored on those function parameters
myNoun etc. You use the parameters to make a big sentence (string).
Then whatever words are passed, the return from the function is a sensible sentence.
function wordBlanks(myNoun, myAdjective, myVerb, myAdverb) {
var result = "";
// Your code below this line
result = "A "+myAdjective+" "+myNoun+" ate my dinner "+myAdverb+", and then I "+myVerb+"the table.";
// Your code above this line
return result;
}
// Change the words here to test your function
wordBlanks("cat", "little", "hit", "slowly");
Still not worgking
Sorry i missed a space
I am kinda stuck with local scope and functions. I think there's a bug here
@kristerChawa I believe there are no bugs there. The description used to be somewhat confusing though.
It says that I should remove the console.log. I've removed it and declared a global variable already but still not working
@kristerChawa Don't touch the
'use strict'; at the start of function. It should be there on its own line.
@kristerChawa It says do not create a global myVar which you have
@sjames1958gm I didn't create a global myVar at first and it's still not working .
Remove line 8
hey guys i just want to know how to call the parameters after the array in seek and destroy challenge, anyone? thanks :D
// global stuff
function name(name) {
return name; // Stuff in the local scope to the function.
}
// More of that global stuff.
@jcfa01
arguments object.
@jcfa01 You do realize that those links are there to help you?
@revisualize i check filter, i thought i knew arguments, guess not haha
@jcfa01 arguments is going to be a new and important concept - used in later challenges.
