## :point_right: bonfire chunky monkey [wiki]

Our goal for this bonfire is to split arr (first argument) into smaller chunks of arrays with the length provided by size (second argument). There are 4 green checks (objectives) our code needs to pass in order to complete this bonfire:

1. (['a', 'b', 'c', 'd'], 2) is expected to be [['a', 'b'], ['c', 'd']]
2. ([0, 1, 2, 3, 4, 5], 3) is expected to be [[0, 1, 2], [3, 4, 5]]
3. ([0, 1, 2, 3, 4, 5], 2) is expected to be [[0, 1], [2, 3], [4, 5]]
4. ([0, 1, 2, 3, 4, 5], 4) is expected to be [[0, 1, 2, 3], [4, 5]]

## :point_right: bonfire reverse a string [wiki]

Our goal for this bonfire is to reverse the provided string just like the image. There are 4 green checks (objectives) our code needs to pass in order to complete this bonfire:

1. The final object is expected to be a string
2. "hello" is expected to be "olleh"
3. "Howdy" is expected to be "ydowH"
4. "Greetings from Earth" is expected to be "htraE morf sgniteerG"

Quick question, in the functional programming, I came across this code as a solution:

function() {
var videos = [
{
"id": 65432445,
"title": "The Chamber"
},
{
"id": 675465,
"title": "Fracture"
},
{
"id": 70111470,
"title": "Die Hard"
},
{
"id": 654356453,
"title": "Bad Boys"
}
];

// Expecting this output...
// [
//     {
//         "65432445": "The Chamber",
//         "675465": "Fracture",
//         "70111470": "Die Hard",
//         "654356453": "Bad Boys"
//     }
// ]
return videos.
reduce(function(accumulatedMap, video) {

// Object.create() makes a fast copy of the accumulatedMap by
// creating a new object and setting the accumulatedMap to be the
// new object's prototype.
// Initially the new object is empty and has no members of its own,
// except a pointer to the object on which it was based. If an
// attempt to find a member on the new object fails, the new object
// silently attempts to find the member on its prototype. This
// process continues recursively, with each object checking its
// prototype until the member is found or we reach the first object
// we created.
// If we set a member value on the new object, it is stored
// directly on that object, leaving the prototype unchanged.
// Object.create() is perfect for functional programming because it
// makes creating a new object with a different member value almost
// as cheap as changing the member on the original object!

var copyOfAccumulatedMap = Object.create(accumulatedMap);

copyOfAccumulatedMap[video.id] = video.title;

return copyOfAccumulatedMap;
},
// Use an empty map as the initial value instead of the first item in
// the list.
{});
}

I'm confused as to how the output is supposedly


// [
//     {
//         "65432445": "The Chamber",
//         "675465": "Fracture",
//         "70111470": "Die Hard",
//         "654356453": "Bad Boys"
//     }
// ]

And not

    // [
//     {
//         "id": "The Chamber",
//         "id": "Fracture",
//         "id": "Die Hard",
//         "id": "Bad Boys"
//     }
// ]
Or even,
[
{
"id": "TheChamber",
"title": "The Chamber"
},
{
"id": "Fracture",
"title": "Fracture"
},
{
"id": "Die Hard",
"title": "Die Hard"
},
{
"id": "Bad Boys",
"title": "Bad Boys"
}
]

Write a function that takes two or more arrays and returns a new array of unique values in the order of the original provided arrays.
In other words, all values present from all arrays should be included in their original order, but with no duplicates in the final array.
The unique numbers should be sorted by their original order, but the final array should not be sorted in numerical order.
Check the assertion tests for examples.

@Philosophist the reduce callback makes a copy of the previous value. so you start with {} as the previous value. you make a copy of that. then you set that copies video.id key to video.title.
That value is returned. then the process repeats except now the previous value is {'<video.id>':'<video.title>'}.
DTing
@dting
Aug 08 2015 00:25
calling reduce on the videos array means that the callback is called with each value in the videos array you can think of it as:
var result = {};
for (var i = 0; i < videos.length; i++) {
var video = videos[i];
result[video.id] = video.title;
}
return result;
Steven Parker
@Philosophist
Aug 08 2015 00:38
Oh, so it's taking video.id as the position in the {} in the array? Like some other earlier examples which had missing number values or number values out of order? And result[] = is another way of writing a sort of push function into {}?

Are "{}" (set?) values always able to operate like that? Like, could

result[video[0]] = video[1];

have worked?

but most people try to avoid using bracket notation when you can use the dot notation unless you have too. For example:
var a = {'1': 2, '1a': 3, '.b': 4}

// throws
a.1
// okay
a['1']

// throws
a.1a
// okay
a['1a']

// throws
a..b
// okay
a['.b']

Anyone up for double-checking my Map the Debris code? For some reason all of the calculations are off by a tiny fraction and I'm pulling my hair out trying to figure it out. I'm sure it's something trivial that I'm overlooking. Any help is appreciated! [cross-posted]
function calculateOP(altitude) {
var GM = 398600.4419;
var earthRadius = 6367.4447;

return Math.round(2 * Math.PI * Math.sqrt(Math.pow((earthRadius + parseInt(altitude)), 3)/GM));
}

function orbitalPeriod(arr) {
var tmpArr = [];

for (var i = 0; i < arr.length; i++) {
var objName = arr[i].name;
var alt = parseInt(arr[i].avgAlt);
var obj = {name: objName, orbitalPeriod: calculateOP(alt)};

tmpArr.push(obj);
}

return tmpArr;
}

Aug 08 2015 01:49
@nogo10 you can use "global" (or more correctly, within scope) functions within other functions. And also return functions that will "remember" the context on which they were created. That's the beauty of closures
David Hewitt
@davidmhewitt
Aug 08 2015 01:50
@chicachicamji Your return statement returns only 1 value. So that code will return the first letter of the last word of the array.
Cristián Berríos
@crisberrios
Aug 08 2015 01:50
@chicachicamji it's because for each iteration you are overwriting the variable "yes".
Also, read the instructions well as it doesn't seem you are trying to do the right thing.
David Hewitt
@davidmhewitt
Aug 08 2015 01:51
@chicachicamji That bonfire wants you to return a string with the first letter of every word capitalised. So you have to find a way to rebuild/edit the string, not return the capitalised letters.
Cristián Berríos
@crisberrios
Aug 08 2015 01:51
Still, if what you want is returning the 1st letter of each array
do the following changes: replace yes for var yes=[];
then instead of yes = ..... do yes.push(....)
chicachicamji
@chicachicamji
Aug 08 2015 01:52
ohhh that makes sense @davidmhewitt @crisberrios and I know, I'm just testing this so it works before I return the string with each letter capitalized
Cristián Berríos
@crisberrios
Aug 08 2015 01:53
push will add new results to the end of the array as a new entry

@alf808 yes! there is an upvote button. I found it. So yes, people vote on articles they like and it makes them appear closer to the top of the list.

for the mutations Bonfire, is there an easier way than this below?
function mutation(arr) {

result = true;

var firstWord = arr[0].toLowerCase().split("");
var secondWord = arr[1].toLowerCase().split("");
var storage = [];

for(var i = 0; i < secondWord.length; i++) {

storage.push(firstWord.indexOf(secondWord[i]));
}

for(j = 0; j < storage.length; j++) {

if(storage[j] < 0) {

result = false;
}
}

return result;
}

mutation(['hello', 'hey']);

function chunk(arr, size) {
// create an empty array to where elements will be pushed in
var splited = [];
// while there is any element on array
while (arr) {
// if size is bigger or equal to array length
if (size >= arr.length) {
// push slice part from arr into splited
splited.push(arr.slice(0, size));
// remove part from original arr
arr.splice(0, size);
}
}

return splited;
}

chunk(['a', 'b', 'c', 'd'], 2);
Well, that's some interesting markup.
@pwdd You'll need to review the condition of your while loop.

@gibsonio FYI,

function mutation(arr) {

var str2 = arr[1].toLowerCase();

for (i = 0; i < str2.length; i++) {

if (str1.indexOf(str2[i]) === -1) {
return false;
}
}
return true;
}
mutation(['hello', 'hey']);

## :fire:Bonfire: Mutations :link:

function mutation(arr) {
return arr;
}

mutation(['hello', 'hey']);

Return true if the string in the first element of the array contains all of the letters of the string in the second element of the array.
For example, ['hello', 'Hello'], should return true because all of the letters in the second string are present in the first, ignoring case.
The arguments ['hello', 'hey'] should return false because the string 'hello' does not contain a 'y'.
Lastly, ['Alien', 'line'], should return true because all of the letters in 'line' are present in 'Alien'.
Remember to use RSAP if you get stuck. Try to pair program. Write your own code.

## :point_right: bonfire chunky monkey [wiki]

Our goal for this bonfire is to split arr (first argument) into smaller chunks of arrays with the length provided by size (second argument). There are 4 green checks (objectives) our code needs to pass in order to complete this bonfire:

1. (['a', 'b', 'c', 'd'], 2) is expected to be [['a', 'b'], ['c', 'd']]
2. ([0, 1, 2, 3, 4, 5], 3) is expected to be [[0, 1, 2], [3, 4, 5]]
3. ([0, 1, 2, 3, 4, 5], 2) is expected to be [[0, 1], [2, 3], [4, 5]]
4. ([0, 1, 2, 3, 4, 5], 4) is expected to be [[0, 1, 2, 3], [4, 5]]

@pwdd yes, going until the arr.length > size would be an approach. However, you'll need to realize that at some point you may have an array that's not divisible by size, so you may have some remaining elements left over.

@rc242
Aug 08 2015 02:34
@pwdd The main difference between splice and slice is that splice modifies the array. This may not be the appropriate approach for some input.
@pwdd ... and slice returns an array, but keeps the original array in tact.
pwdd
@pwdd
Aug 08 2015 02:35

@rc242
Aug 08 2015 02:36
@pwdd This is probably getting ahead of your experience on here (or as a developer), but when you're providing a "service" (e.g., a function), others may not be expecting your service to modify their input variables.
@pwdd Again, this is probably getting ahead of things, but you may want to think of local variables like this, "do I need all this data right now?" In this example, you only need the input array and chunks off it. You don't need the input array x2 at any point.

Hi all. I was working on Bonfire: Seek and Destroy yesterday, which I was eventually able to successfully code. But I didn't use an Array.filter()
Can someone help show me how you would use an Array.filter() in this situation?
Rex Schrader
@SaintPeter
Aug 08 2015 05:15
@davidfaillaii Sure
@davidfaillaii Do you want to share your code, or just get a general description of how .filter works?
or, I guess, how it applies?
David Failla
@davidfaillaii
Aug 08 2015 05:16
Yes, how it applies
Rex Schrader
@SaintPeter
Aug 08 2015 05:17
ok, so if you break down the problem it it's most elemental parts, what you're doing is deciding if a number stays or goes from an array, right?
David Failla
@davidfaillaii
Aug 08 2015 05:17
I understand the theory of how the .filter works, but couldn't figure out/ get it to work in this situation.
wontoan
@wontoan
Aug 08 2015 05:17
@davidfaillaii .filter simply replaces the for loop and .push in one step.
Rex Schrader
@SaintPeter
Aug 08 2015 05:17
With array.filter, you can process each element in an array and, if you return 'true' it keeps the value and 'false' it leaves the value out
So, yeah, what @wontoan said - it just simplifies the loop. No need for an itterator and no need for a temp array to store the answer in
David Failla
@davidfaillaii
Aug 08 2015 05:20
is .filter always used with .filter(function(){.......?
Ross Kaffenberger
@rossta
Aug 08 2015 05:20
@davidfaillaii usually like that, yes
Rex Schrader
@SaintPeter
Aug 08 2015 05:20
@davidfaillaii mostly, but not always. You can define your filter function elsewhere in your code and just pass in the function name
Like this:
function filterThing(thing) {
return thing > 5;
}
var filtered = arr.filter(filterThing);
David Failla
@davidfaillaii
Aug 08 2015 05:22
ah, ok
Rex Schrader
@SaintPeter
Aug 08 2015 05:22
The idea would be if you had a common filter that you were applying in a bunch of different places, it might make sense to define it as a function elsewhere
It can also potentially make your code more readable
Here is my S&D solution:
// Functional Programming Solution
function destroyer(arr) {
// Get just the passed arguments
var args = Array.prototype.slice.call(arguments,1);

return arr.filter(function(a) { return (args.indexOf(a) === -1);});
}
David Failla
@davidfaillaii
Aug 08 2015 05:25
@SaintPeter Thank you for sharing. I'm a little confused about what args.indexOf(a) === -1 is doing
wontoan
@wontoan
Aug 08 2015 05:27
array.indexOf('what you're looking for in the array');
If 'what you're looking for' is there, it'll tell you at which index it's found (array[0], array[1], etc.)
If it's not there it'll return -1.
Rex Schrader
@SaintPeter
Aug 08 2015 05:27
@davidfaillaii args from the line above is an array of all of the arguments passed in, excluding the first one (which is the array to search). .indexOf searches an array for a given value (in this case a) and, if it finds it, returns the index of that item. If it doesn't find it, it returns -1 (because, of course, 0 is a valid answer for an index in an array)
@davidfaillaii So what I've done is kinda turned the problem on it's head. Rather than searching the array for each "destroy" value, I'm instead searching the list of possible "destroy" values for each value in the array. If it's not found (indexof === -1), then it returns true, meaning that it is kept. If it were found (indexof !== -1), then we'd "destroy" it - return false and remove it from the array.
David Failla

is there a way to complete this exercise without converting the arguments into an array?
Rex Schrader

Aug 08 2015 05:31
No
Pretty much anytime you have an unknown amount of arguments you're going to need to access the arguments object
David Failla
@davidfaillaii
Aug 08 2015 05:32
ok, that also confused me at first

Aug 08 2015 05:32

I suppose it's theoretically possible to use the 'raw' arguments object - you could, for example, use a for..in loop

Good. In case you were wondering @ckent20, the problem was
var contacts = ['bob', 'mary'];
So console.log(contacts[1].phoneNumber); is actually
console.log('mary'.phoneNumber);
Easily fixed with var contacts = [bob, mary];

one of the javascript challenges
essentially, i'd like my rock paper scissors and paper game to restart if the computer and user guesses the same

var userChoice = function(){
var choice = prompt("Do you choose rock, paper, scissors or rope?");
return choice;
}

var computerChoice = function(){
var choice = Math.random();
if (choice <= 0.25) {
choice = "rock";
} else if(choice <= 0.5) {
choice = "paper";
} else if(choice <= 0.75) {
choice = "scissors";
} else {
choice = "rope";
}
return choice;
}

var compare = function(choice1, choice2) {
if(choice1 === choice2) {
var newUserChoice = prompt("You tied! Play again... Do you choose rock, paper, scissors or rope?");
compare(newUserChoice, computerChoice());
} else if (choice1 === "rock"){
if (choice2 === "paper"){
return "paper wins";
}else {
return "rock wins";
}
} else if (choice1 === "paper"){
if (choice2 === "scissors"){
return "scissors wins";
} else if (choice2 === "rope"){
return "rope wins";
} else {
return "paper wins";
}
} else if (choice1 === "scissors"){
if (choice2 === "rock"){
return "rock wins";
} else {
return "scissors wins";
}
} else if (choice1 === "rope"){
if (choice2 === "rock"){
return "rock wins";
} else if (choice2 === "scissors"){
return "scissors wins";
} else {
return "rope wins";
}
} else {
return "Invalid user input";
}
}

compare(userChoice(), computerChoice());

oops

galacticfan
@galacticfan
Aug 08 2015 09:05
@morley92 in your compare code, if the two equal each other you need to then write:
compare(userChoice(), computerChoice());
this will initiate the whole process again
Jonny Morley
@morley92
Aug 08 2015 09:06
you'd think so, but instead when it asks for input after an equal comparison, the next input will never yeild an output :/

you have to return the compare
otherwise the whole result will be undefined
you're code is not running in any return statements in this case

@galacticfan
Aug 08 2015 09:35
@tawnytron type needs to equal submit
and the btn bit is the name of the css class in the bootstrap css
so you need to assign a class to the button using class='btn'
Tawny Walling
@tawnytron

having problems also with..:04. Inside of the loop, add code to call printPerson, passing in the element of the array that the loop is currently at.
1. At the very bottom of the file, call the list function. The list function should then loop through every member of the contacts array and print its information.

you need to write var before i in your for loop
Randy Goldsmith

how would u print bob ?

console.log(contact[0])..if i wanted to print all of his informatino
information
Omar
@oab00
Aug 08 2015 10:37
how would you print it using the function printPerson ?
Randy Goldsmith
@Dueldrawer8
Aug 08 2015 10:38
printPerson(contact[0]) right?
Omar
@oab00
Aug 08 2015 10:39
correct !
now change that to be inside a for loop :p
Randy Goldsmith
@Dueldrawer8
Aug 08 2015 10:40
but i want it to print both contact infos.. not just the first elements
Omar
@oab00
Aug 08 2015 10:40
so that it prints printPerson(contact[0]) first round
then prints printPerson(contact[1]) on second round
ah
sorry then you can use console.log(contact[0]) instead xD
Randy Goldsmith
@Dueldrawer8
Aug 08 2015 10:42
im suppose to call the function list() and its suppose to list all of there contact info all at the same time
Omar
@oab00
Aug 08 2015 10:42
ah right so you need a for loop to loop through the contact array and console log it
Randy Goldsmith
@Dueldrawer8
Aug 08 2015 10:42
well once again these are the instructions..
1. Create a function called list that does not take any parameters.
2. At the start of the function, define a variable to store the number of items in the contacts array. Call it contactsLength.
3. All of the items in an array are numbered, starting at 0. To cycle through all of the elements of the array, create a for loop that cycles from 0 up to one less than the number of items in the contacts array.
4. Inside of the loop, add code to call printPerson, passing in the element of the array that the loop is currently at.
5. At the very bottom of the file, call the list function. The list function should then loop through every member of the contacts array and print its information.
so inside the for loop.. i do need to call the function printPerson
Omar
@oab00
Aug 08 2015 10:43
right so what you said first is correct console.log(contact[0]) you just need to stick it in a for loop
Randy Goldsmith
@Dueldrawer8
Aug 08 2015 10:44
this is frustrating.. still not working

function printPerson(person) {
console.log(person.firstName + " " + person.lastName);
}

function list(){
var contactsLength = contacts;
for(var i = 0; i < contacts.length; i++) {
console.log(contacts[0]);
}
}

list(contacts);
Oops, try again. It looks like your list function didn't console.log "Bob Jones". Did you remember to call list(); after creating it?
Omar
@oab00
Aug 08 2015 10:45
so close!
how would u make the for loop print console.log(contacts[0]); first round
then console.log(contacts[1]); second round

Omar
@oab00
Aug 08 2015 10:48
correct i = 0 on first round
and i = 1 on second round
don't you think you can replace 0 with something inside console.log(contacts[0]);

@oab00 it's for the chunky monkey challenge
function chunk(arr, size) {
var result = [];
var innerArr = [];
var counter = 1;

for (var i = 0; i < arr.length; i++) {
if (counter <= size) {
innerArr.push(arr[i]);
counter++;

if (i+1 === arr.length) {
result.push(innerArr);
}
}
else {
result.push(innerArr);
innerArr = []; // clear array (the super dangerous way)
counter = 1; // reset counter
innerArr.push(arr[i]);
}
}

return result;
}

chunk([0, 1, 2, 3, 4, 5], 2);
for some reason it
returns [ [ 0, 1 ], [ 2, 3, 4 ] ] instead of [ [ 0, 1 ], [ 2, 3 ], [ 4, 5 ] ]
but it works for the rest of the arrays that are tested

but still get funny results:
function chunk(arr, size) {
var result = [];
var innerArr = [];
var counter = 1;

for (var i = 0; i < arr.length; i++) {
if (counter <= size) {
innerArr.push(arr[i]);
counter++;

if (i+1 === arr.length) { // if at end of loop
result.push(innerArr);
}
}
else {
result.push(innerArr);
innerArr = []; // clear array (the super dangerous way)
counter = 1; // reset counter
innerArr.push(arr[i]);

if (i+1 === arr.length) { // if at end of loop
result.push(innerArr);
}
}
}

return result;
}

chunk([0, 1, 2, 3, 4, 5], 2);
@oab00 oh really?
Omar

Aug 08 2015 11:00
if (counter <= size) {

Randy Goldsmith
@Dueldrawer8
Aug 08 2015 11:06
having problems with this : 04. The twist comes here: in the body of the loop, rather than printing out every single item in the array, add an if statement that checks to see if the lastName property of the object is equal to the lastName argument. Have the function run printPerson on the person if and only if the lastName property of the person matches the lastName argument.
to call a property of an object i thought you used the dot notation..
like person.lastName
Omar
@oab00
Aug 08 2015 11:10
@galacticfan now I know why it works
it's because you're doing innerArr.push(arr[i]); in the else statement
essentially doing the job that counter = 0 should do
without incrementing counter
galacticfan
@galacticfan
Aug 08 2015 11:11
of course, I need to increment the counter when I do it, because I've just added an element to the inner array, you're a genius, thanks @oab00

yeah i just didn't know if it was person.lastName or something else.. which it was something else
i guess since im using for loop and an array it has to be with the [i]
whenever i read thecode.. it makes perfect sense
but looking at a problem and trying to think how to do it.. hard for me to do lol
need to study or do more of these excercises
with the arrays and objects
well im off to bed.. thanks for help

Hey @cjg040103, a good practice is to make functions which work whatever the input, so you should really make a method for the strings to add together as many times as the user wants (with num)
ie use a for loop to reiterate dynamically to the num size
you're not going to reap the benefits of practical work like that xD

@SarthakAdhikari You need to check if the first letter of your name matches with any letters of the text var, then push the follow letters that construct your name into the hits var
/*jshint multistr:true */
var text = "Matt Bob Eric Eric Bob Matt Eric Bob Matt"
var myName = "Matt"
var hits = []

for (var i = 0; i < text.length; i++) {
if (text[i] === myName[0]) {
for (var x = i; x < (myName.length + i); x++) {
hits.push(text[x])
}
}

@cjg040103 Make it so that if the length of str is larger than the num, take out the first num -3 letters of str and return it
otherwise return str on it's own
you can use the splice function to take out the first num - 3 letters

I was wondering if there is a more elegant way of writing this piece of code? It was from the "Finders Keepers" bonfire:
function find(arr, func) {
var num;
var boo = arr.some(func);

if(boo === true) {

for(var i = 0; i < arr.length; i++) {
num = arr[i];
if(func(num) === true) {
return num;
}

}

}
}

find([1, 2, 3, 4], function(num){ return num % 2 === 0; });
Matthew Barber

Aug 08 2015 15:41
@DanStockham
function find(arr, func) {
for(i = 0; i < arr.length; i++) {
if(func(arr[i])) {
var element = arr[i];
break;
}
}
return element;
}
not sure if I should use break like that, seems like it's ineffecient or dangerous heh
elegant wise you've got it really, I didn't use some then
Dan Stockham
@DanStockham
Aug 08 2015 15:42
Alright, it just seems like .some() is pretty useless.
If I am testing func using a conditional, then boo is like the third wheel.

DTing
@dting
Aug 08 2015 15:46
@DanStockham you can use some there like this:
function find(arr, func) {
var num;
arr.some(function(e) {
if (func(e)) {
num = e;
return true;
}
});
return num;
}
some is like a forEach but you can exit early by returning true.

Aug 08 2015 16:12
@ShaklinSyed Don't forget to check if the arguments are number or not because one of the tests checks to see if ([3]) + (2) is undefined because [3] is an object/array and not a number and javaScript will try to convert the [3] to a number and thus returning 5 as expected (but FCC expects that operation to be undefined.
Also, return a function that sums the x of the OUTER function and the first argument of THAT function.

Aug 08 2015 16:15
@ShaklinSyed in the IF statement, put the returned ANONYMOUS function inside ELSE. and inside that anonymous function you should return the sum of x and the first argument of the anonymous function. (remember closures)
Also have in consideration that you also have to check if the argument in the inner function is a number or not.

@Optmistic What you are doing there is applying the procedure you need to the WHOLE string! You need to do that with each word of the string and you can do that two ways... using the String.prototype.split() method or the String.prototype.match() method (which takes a regex or a string as a parameter)

@SerenityFL
Aug 08 2015 16:25
Instructions say to do this: Instead of creating a new style element, try removing the h2 style declaration from your existing style element, then replace it with the class declaration for ".red-text". It sounded to me like they didn't want me to put in an html element
Luis Felipe López G.
@luishendrix92
Aug 08 2015 16:25

@Optmistic Have this pseudocode in mind and use the tools I gave you:

Grab every word inside the string and store it in an array. (using match or split).
To each of the words do this: Replace the first character with its uppercase equivalent and add the rest of the word to it. (you did it right using split, charAt() and toUpperCase there but the .toLowerCase at the end should not be there).
Join the array and return it as a string.

You can do this by using a for-loop or the String.prototype.replace() along with String.prototype.match()

It is short hand for: var result = []; for (...) { // do something with result; } return result; https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/Reduce Randy Goldsmith @Dueldrawer8 Aug 08 2015 17:37 1. In this new function, you want to create a new contact object like bob and mary. Instead of having this object's property values be filled with strings though, set them to the appropriate function parameters passed in. 2. Add this new contact object to the contacts array. how do i do those two directions?

Matthew Barber @Honno Aug 08 2015 17:38 haha yea weird David Hewitt @davidmhewitt Aug 08 2015 17:39 @Honno But yes, none of the variables are global because you don't put a this in front of them. So the only things accessible from outside the class are the methods. Feners4 @Feners4 Aug 08 2015 17:39 @jbmartinez should I switch it to observe? Matthew Barber @Honno Aug 08 2015 17:39 @davidmhewitt Mhm, it's just redundant asking for a function to get those values, and then assigning them to a global var anyway heh Feners4 @Feners4 Aug 08 2015 17:40 @jbmartinez even with $observe it doesnt work..

@Azhagan write a function that will give you the symmetric difference of 2 arrays. Then use that function as the callback to reduce.

Convert the characters "&", "<", ">", '"' (double quote), and "'" (apostrophe), in a string to their corresponding HTML entities.

Came up with this to solve Finders Keepers:

function find(arr, func) {
var result;
if (arr.some(function(number) {result = number;return func(number);}))
return result;
else
return;
}

find([1, 2, 3, 4], function(num){ return num % 2 === 0; });

I seriously tried to use the closure inside the paramenter but I had to create a separate function inside arr.some and pass the function in the parameter as the test to return TRUE or FALSE.

I have, I think, three if statements in mine.
My basic process was this:
1. Calculate the total change required
Juan Martínez
@jbmartinez
Aug 08 2015 18:06
@Feners4 I've never used directives that way, I think you have to use the $compile method Raincode @Raincode Aug 08 2015 18:07 @luishendrix92 What's wrong with this? function find(arr, func) { var num = undefined; for (var key in arr) if (func(arr[key])) { num = arr[key]; break; } return num; } Marc Davenport @oneate7 Aug 08 2015 18:07 1. If the change is more than what's in the drawer, insufficient. If it's the same, closed. Chocobowings @chocobowings Aug 08 2015 18:07 @oneate7 up to that i am ok Dan Stockham @DanStockham Aug 08 2015 18:08 So this is what I have so far: function drop(arr, func) { var num; for( var i = 0; i <= arr.length; i++) { console.log(func(arguments.length)); if(func(i) === false) { arr.shift(); } else { } } return arr; } drop([1, 2, 3], function(n) {return n > 5; }); Marc Davenport @oneate7 Aug 08 2015 18:09 After that, I basically used a do loop nested in a for loop to subtract the largest bill from the change total until the remaining change was less than the current bill or the drawer was out of that bill. The for loop moves through the bills in reverse order, the do loop does the subtraction from the change total as well as the drawer. Juan Martínez @jbmartinez Aug 08 2015 18:09 @Feners4 I used a different code in my solution, but it's not very elegant: ng-src='{{item.image || item.author.picture}}' Marc Davenport @oneate7 Aug 08 2015 18:09 @chocobowings Did that make any sense? lol M Used @mildused Aug 08 2015 18:09 Spoiler Alert function drop(arr, func) { return arr.filter(func); } Spoiler Alert Luis Felipe López G. @luishendrix92 Aug 08 2015 18:10 @Raincode First of all, just declaring the variable initializes it as "undefined" so leave it as var num; Second, you are breaking the function using break after your test in the IF statement returns true, and it never gets to return your "num" This message was deleted Chocobowings @chocobowings Aug 08 2015 18:10 @oneate7 yes it makes sense. I will try your approach to see if i can solve it. Thanks ! :) Marc Davenport @oneate7 Aug 08 2015 18:11 No problem... good luck! Raincode @Raincode Aug 08 2015 18:11 @luishendrix92 Doesn't brake just exist the inner-most loop or switch-statement? *exit Luis Felipe López G. @luishendrix92 Aug 08 2015 18:13 @Raincode Ohh I see, let me open the console. Raincode @Raincode Aug 08 2015 18:15 @luishendrix92 Quoting MDN: "The break statement terminates the current loop, switch, or label statement and transfers program control to the statement following the terminated statement." Luis Felipe López G. @luishendrix92 Aug 08 2015 18:15 @Raincode It is working... can'tsee what you did wrong (if your bonfire tests fail) Raincode @Raincode Aug 08 2015 18:16 By saying "What is wrong with this" I didn't inted to say it actualy is not working, I was implying the question why the solution with arr.some would be better or clearer I guess it was my mistake, since I did that in the help section, sorry. Luis Felipe López G. @luishendrix92 Aug 08 2015 18:16 Your code makes sense and it's more readable than arr.some for those who don't know what "some" is. I really wanted not to use Arr.some but I went with it anyway. Raincode @Raincode Aug 08 2015 18:17 Sounds legit :) Luis Felipe López G. @luishendrix92 Aug 08 2015 18:18 It's just that the iterative array methods are the darling of some javascript develpers, instead of using fors and whiles they use map, forEach and reduce. Less code to write I guess, more functional prowess perhaps.

Juan Martínez @jbmartinez Aug 08 2015 18:29 @Feners4 I like this shorter way because is easier, less code == less bugs, but it's not very flexible @Feners4 the custom directive is better when you have many alternatives or you're working in a large project.

In the bash profile, beneath the aliases, on a new line, type

Save the file and press enter to write the filename.

I do that

This is my solution to Bonfire #27

function unite(arr1, arr2, arr3) {
var flat_arr = [arr1, arr2, arr2].reduce(function(a,b) {return a.concat(b);});
var original_val_arr = flat_arr.filter(function(value, index){return index === flat_arr.indexOf(value);});
return original_val_arr;
}

unite([1, 2, 3], [5, 2, 1, 4], [2, 1]);
unite([1, 3, 2], [1, [5]], [2, [4]]);

The problem here is that it seems logical and does work in a JS console but doesn't work in the Bonfire environment.

@tylerstonge better to indent your code to make it more readable:
// Break it up.
var d1 = 0;
var d2 = 0;
var result = [];
result[d1] = [];
for (var i = 0; i < arr.length; i++) {
if (d2 >= size) {
d1++;
d2 = 0;
result[d1] = [];
}
result[d1][d2] = arr[i];
d2++;
}
return result;
}
chunk(['a', 'b', 'c', 'd'], 2);

@softeg you'll need to attach your functions to the Person object. You can do this by adding "this.getFullName = function() ..."

@softeg all u methods are "public methods" part of ur person class.. u need to add "this" keyword so they can be acccessed from outside

## :fire:Bonfire: Chunky Monkey :link:

function chunk(arr, size) {
// Break it up.
return arr;
}

chunk(['a', 'b', 'c', 'd'], 2);

Write a function that splits an array (first argument) into groups the length of size (second argument) and returns them as a multidimensional array.
Remember to use RSAP if you get stuck. Try to pair program. Write your own code.

@tylerstonge that's fine, I suppose. I'm sure it does the same things as implementations using Array.splice().

@tylerstonge Well, I was talking more like using Array.splice to give you an array rather than iterating over your input array to generate the output.
