What would i be doing wrong? myData is supposed to equal the first value of myArray.
// var ourArray = [1,2,3];
// var ourData = ourArray[0]; // equals 1

var myArray = [1,2,3];
// Only change code below this line.
var myData = [0];
Charles Milam
@CharlesMilam
Oct 26 2015 00:22
You are setting myData to a new array with a single element of 0.
Garrett Schultz

Oct 26 2015 00:22
soooooo just take out the equal sign?
Charles Milam
@CharlesMilam

Check out the comment, and do what is similar to ourArray0, but your myData.
oops, formatting
ourArray[0]

When used like that you are referencing an element within the array, as you had it, you were assigning a new array.

@gratschultz2013 quotes around srt4 and scionFRS
Charles Milam
@CharlesMilam
Oct 26 2015 00:43
@gratschultz2013 are you using srt4 as a variable name? Otherwise, those car names need to be in quotes, so they are strings.
Garrett Schultz
@garettschultz
Oct 26 2015 00:44
aha @Aoxom that was the problem, forgot to use quotes since its like a string.

well, see this is my issue. i type that exact thing in my editor outside of FCC and it says errors but in FCC it works!!!!!!!!!!!!!
ahhh outside of FCC the only way the code works and returns my answer is if it looks like this:
var cars = ["srt4","frs"]; myCars = cars[1];
Garrett Schultz
@garettschultz
Oct 26 2015 00:51
meaning i didnt have to use var cars = myCars[1];

Hello, I am doing the Waypoint Challenge. The instructions say to add a green background to my form element to #cat-photo-element { background-color: green; }

I've tried this many times and I've created a class called .green-background {
background-color: green
}
I'm stuck the form element also has the id=cat-photo-form.

Charles Milam
@CharlesMilam
Oct 26 2015 01:08
what you are using outside of FCC is correct. Not sure why FCC accepts it. Without the quotes Javascript is going to treat srt4 and frs as variables. So unless you did something like:
var srt4 ="SRT4";
then it is going to error out because srt4 has not been defined anywhere.
with the # is saying that it is an id and not a class.

Can anyone help me trouble shoot the search functionality of my twitchtv zipline?
I'm using List.js. When I hardcode the links, the functionality works but it breaks when I use the API.

API version:

Hard coded version:
http://codepen.io/daniel-chung/pen/JYLyVL?editors=101

@CharlesMilam
Oct 26 2015 01:17
@daniel-chung successF(data, userName, className) where is that defined?
When you say "I use the API" are you talking about the Twitch API? Can you get the Twitch API to do anything for your?
errr for you?
I know I have also seen folks saying you have to use JSONP and not straight JSON when discussing the Twitch API, but not sure if it applies here. I have not yet done that one. You might also want to ask for some help here, which is help chat dedicated to ziplines => https://gitter.im/FreeCodeCamp/HelpZiplines
Daniel Chung
@daniel-chung
Oct 26 2015 01:24

@CharlesMilam thanks for your response!

The successF is a parameter of the getUserStreams() function.

Yes, I'm using the Twitch API and that's working for me. The issue I'm having is that the List.js functionality doesn't seem to be working when I use the Twitch API. My huntch is that jQuery isn't loading fast enough or isn't fully interacting with the list.js.

hey guys im in 106 (Waypoint: Target HTML Elements with Selectors Using jQuery). i've completed it but I just want to understand what they mean when they say: Note that we've already included both the jQuery library and the Animate.css library in your code editor. So you are using jQuery to apply the Animate.css bounce class to your button elements.

@96street jQuery is a collection of javascript libraries. Basically when a jQuery library is referenced you are actually referencing a whole bunch of javascript code that has been been created into a method. This allows you to do more things with javascript without writing out as much code. "write less, do more"

h4r1m4u
@h4r1m4u
Oct 26 2015 02:07

@96street what @CharlesMilam says. for example, if you want to use jquery in your web page, you first need to import it in your <head>, e.g. like so:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>

same with animate.css. without importing these libraries first, you won't have access to the jquery functions or the animate.css classes

Lê Viết Hoàng Dũng
@nangtrongvuon
Oct 26 2015 02:07
@m-farooqui you don't put a class in a div like that, you style the class in your style section
<style>
.gray-background {
background-color: gray;
}
</style>
96street
@96street
Oct 26 2015 02:09
@h4r1m4u so for every page you use jQuery, do you use that same line of code: <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
Lê Viết Hoàng Dũng
@nangtrongvuon
Oct 26 2015 02:09
then you just give the div a class:
<div class="gray-background> thingy with grey background </div>
h4r1m4u

Oct 26 2015 02:09
@nangtrongvuon it's just a spelling difference. grey is UK english, gray is American english

This code passes 4/6 tests. For some reason on this one, it's looping 7 times instead of just arr.length times.
function where(arr, num) {
// Find my place in this sorted array.

var count = 0;
arr.sort(function(comp){

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

if (num > arr[i]) {
//console.log(count);
count++;
//console.log(count);
return count;

@JustinJ01 Practice is definitely the most important part in my opinion. That being said, if you have no experience in programming it could be useful to take notes. What I have found to be the best is to copy the code into a text editor and comment out what the code is doing. That way I can go back to reference what I have done and how it works

if (num > arr[count]) {

}).indexOf(num);
}

Oct 26 2015 02:26
@matty22 Isn't the array already sorted for you? The first comment says to find the index in the "sorted array" , giving the impression that the array is already sorted.
I would think you could just do arr.indexOf(num);

The challenge asks you to find its index. So if you push it in, then sort it, you can do indexOf(). The problem being that if there are two "50" then indexOf() doesn't know which to grab the index for.

Well I tried going that route in the bonfire and it didn't pass. For example, this:
function where(arr, num) {
// Find my place in this sorted array.

/* var count = 0;
arr.sort(function(comp){

if (num > arr[count]) {

count++;
return count;

}

});

return count; */

arr.push(num);
arr.sort();
return arr.indexOf(num);

}

where([5, 3, 20, 3], 3);
Returns 1, when it should return 0.
Notice the comments around my actual code.

@matty22 sort is sorting by unicode code in that example, so 20 is before 3

@matty22 Going forward, if they don't tell you to alter the array, say by pushing the compare number, then it is best to leave it alone, as future tests might check if the compare number even exists in the array, or that the array length is the same, stuff like that.

So my code works but it adds the ellipsis to any string, not just ones with 3 or more characters, and it won't pass the last test. Do I need to use a if/elseif statement with >=3 in my control flow?
function truncate(str, num) {
// define local variables
var stringToTrim = str;
var trimAt = num;
//logic below
if (stringToTrim.length>trimAt){
stringToTrim = stringToTrim.slice(0, trimAt-3) + ("...");
//stringToTrim = stringToTrim + ("...");
} else{
stringToTrim.slice(trimAt);
}
return stringToTrim;
}

truncate("A-tisket a-tasket A green and yellow basket", 11);

@navicyclical yes. consider what happens for a string 'A-' and num 1 here:

stringToTrim = stringToTrim.slice(0, trimAt-3) + ("...");

this translates to stringToTrim = stringToTrim.slice(0, -2) + ("...");the (0, -2) slice here will be an empty string

Oct 26 2015 05:20
creative way to do it
var quotient = 4.4 / 2.0; // equals 2.2
var product = 2.0 * quotient + 0.6; // equals 5.0

// Only change code above this line.
// We use this function to show you the value of your variable in your output box.
// You'll learn about functions soon.
(function(y){return 'product='+y;})(product);

@techlab23 why couldnt you just replace the 0.0 with 2.5?
or just change it to var product = 5.0;

$c = a \times b$ then $b = \frac{c}{a}$
so
$5.0 = \frac{2.0}{x}$
then
$x = \frac{5.0}{2.0}$
or
$x = 2.5$

i see. in the object constructor function if you use the word 'this', it will make the property of function public. if you don't use 'this', the property/function will be private
private properties and functions cannot be accessed from the outside of the object, whereas public ones can

@h4r1m4u

so in the Car() constructor function, 'gear' is a public property because it uses the word 'this'. whereas the function addStyle() is private - you cannot call it on the created object: myCar.addStyle() won't work
but you can use the getGear() function from the outside, because it's public: myCar.getGear() is completely valid

Guys I have a question about jQuery's event delegation. I have a hover event for the parent element $('.grid') that will fire for all $('.cell') and change the background colour of every .cell. Now I also have another element $clearBtn with a .click even that will fire for all .cell. However, when the button is clicked, it doesn't have any effect on .cell. Here's a code sample if it helps. $grid.on('mouseenter mouseleave', '.cell', function(event) {
// Fill the cell
$(this).css('background-color', '#666'); }); // end hover var$clearBtn = $('.btn-clear'); // When user clicks on clear button$clearBtn.on('click', '.cell', function() {
// Reset cells' bg colour to white.
$(this).css('background-color', '#fff'); }); // end click h4r1m4u @h4r1m4u Oct 26 2015 06:33 @abeermorssy $clearBtn.on('click', '.cell', function() {

// Reset cells' bg colour to white.
$(".cell").css('background-color', '#fff'); }); // end click Vivek @vivek28111992 Oct 26 2015 06:35 @h4r1m4u can you write solution for me?

William @waruiz Oct 26 2015 07:13 it checks out as an array basically looks like var students = [ {name:'string', grades:num}, {name:'string', grades:num}] I can't tell on the last question :/ h4r1m4u @h4r1m4u Oct 26 2015 07:15 can't tell because you don't understand what i'm asking or you're not sure based on your code? @waruiz William @waruiz Oct 26 2015 07:17 @h4r1m4u I'm not sure how to find out which loop it belongs to, probably why I shouldn't have gone this route but now I want to figure where the undefined is coming from I know when I print to the page undefined appears before any of the <h2>'s and <p>'s if that's any indication....I'm not sure what I'm not seeing h4r1m4u @h4r1m4u Oct 26 2015 07:20 i suspect it happens as part of the inner loop. the 'for in' loop iterates over all object properties, including those inherited from prototypes. you can use hasOwnProperty() to make sure that it iterates over the properties attached to the object only. see this for reference: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...in  for (var key in currentStudent) { if (currentStudent.hasOwnProperty(key)) { if (key === 'name') { HTML += '<h2>Student: ' + currentStudent[key] + '</h2>'; } else { HTML += '<p>' + key + ' : ' + currentStudent[key] + '</p>'; } } } try to adjust the inner for loop like this see if you still get the undefined output @waruiz Ngaosathe @ThekhoN Oct 26 2015 07:22 Guys can someone tell me why this recursive function doesn't run as intended? var i = 10; function printNum(){ console.log(i + "<br>"); while(i-->1){ printNum(); } } printNum(); William @waruiz Oct 26 2015 07:23 thanks @h4r1m4u I'll try and read up on hasOwnProperty() CamperBot @camperbot Oct 26 2015 07:23 waruiz sends brownie points to @h4r1m4u :sparkles: :thumbsup: :sparkles: :star: 330 | @h4r1m4u | http://www.freecodecamp.com/h4r1m4u Ngaosathe @ThekhoN Oct 26 2015 07:24 It runs fine when i run it with document.write though :worried: var i = 10; function printNum(){ document.write(i + "<br>"); while(i-->1){ printNum(); } } printNum(); Qadir Pervez @qadirpervez Oct 26 2015 07:25 do you know the difference between console.log() and document.write(); @ThekhoN Ngaosathe @ThekhoN Oct 26 2015 07:25 yes never mind it's working fine now...Weird!

Kasun Weerasinghe @kasunw310 Oct 26 2015 11:30 hi guys.. i need help on a way point : see below for prompt: Waypoint: Manipulate Arrays With pop Another way to change the data in an array is with the .pop() function. .pop()is used to "pop" a value off of the end of an array. We can retrieve this value by performing pop() in a variable declaration. Any type of variable can be "popped" off of an array. Use the .pop() function to remove the last item from myArray. here's the code : var myArray = ["John", 23, ["cat", 2]]; how do i use the pop() method to remove the last item from myArray? h4r1m4u @h4r1m4u Oct 26 2015 11:32 myArray.pop(); lnuic @lnuic Oct 26 2015 11:38 myArray=myArray.pop(); @kasunw310 Aleksander Gębicki @Takumar Oct 26 2015 11:41 @kasunw310 please don't aks the same question on different channels.

My guess is that this is your problem since I don't see anything in your code to handle it. DTing @dting Oct 26 2015 12:02 @coderNoob you didnt change the case of the first letter of "after" to the case of the "before" first letter case lol Aleksander Gębicki @Takumar Oct 26 2015 12:02 @catapixel you are right: "NOTE: Preserve the case of the original word when you are replacing it. For example if you mean to replace the word "Book" with the word "dog", it should be replaced as "Dog"" @coderNoob check for upper and lower case.

Tyler Moeller @TylerMoeller Oct 26 2015 16:06 @Coira Yes, I could do that instead to solve the goal, but I'm trying to have getData() send each piece of data one at a time. @nickdearing88 change your solution to three lines rather than 6 Coira Ellison @Coira Oct 26 2015 16:09 @TylerMoeller hmm. maybe setInterval should be in getdata? Tyler Moeller @TylerMoeller Oct 26 2015 16:10 @Coira yes, that would work too, but the setInterval is just simulating a file write. I'm trying to get this to work with callback functions. Coira Ellison @Coira Oct 26 2015 16:13 ah, i'm lost as to what you want :p as callback() is in a for loop, setTimeout is being called x times simultaneously, rather than once every second Roma @NPrayder Oct 26 2015 16:14 hello everyone iamlimo @iamlimo Oct 26 2015 16:14 Hello guys how do u Hod oops sorry for the typos Roma @NPrayder Oct 26 2015 16:15 good, how u?

@c0d9x there are multiple ways to resolve it: a) delete/comment out the .red-text class from the CSS, b) delete/comment out its font-family property, c) comment out the lobster font import at the top of the code pane
Arnis Jaundzeikars
@SangSatori
Oct 26 2015 18:09
As far as general practice goes, I'm sure 'red text' should make text red without any other side-effects - the font-family doesn't really belong there. I'd remove that, but it's good to understand what works how - and yes, don't use !important - it's a last resort to override everything else and gets out of hand quickly.
h4r1m4u
@h4r1m4u
Oct 26 2015 18:15
actually, generally you want to avoid unsemantic class names like .red-text altogether. what if at some point of your project the stakeholders decide that the text should be green? suddenly you have a .red-text class with color: green which is really confusing. if the project is big, it may be really difficult to change all the .red-text classes to .green-classes. if you use a semantic class name instead, say .priority-1, you can freely change its CSS rules in the future without creating confusion or having to change your HTML code.

return str.split(' ').charAt(0).toUpperCase;
}

}

Oct 26 2015 18:33
@SangSatori : Ah I see. Well I’ve worked at 2 agencies before and I am pretty sure they are a lot worse. If they let you get away with that in a product company then the senior devs or leads are probably not as good as they claimed to be while getting hired. But then again not a lot of developers take CSS seriously. It’s almost harmless. Poor thing.

@Skiippa str.split(' ') returns array. charAt() is not an array method, it works on a string

@Skiippa the console is a good place to see what your script is doing. Have you been using it?

Oct 26 2015 18:36
@Skiippa In addition, .toUpperCase() is a function, not a variable, and so needs parentheses (when you re-fiddle your function)

@Skiippa what @h4r1m4u is saying is that when you call str.split(' '); the result of that function is an array of strings, i.e. ["This", "was", "recently", "a", "string"]
h4r1m4u
@h4r1m4u
Oct 26 2015 18:40
@Skiippa str.split(' ') returns an array, eg. the result of (My dog likes food).split(' ') will be ['My', 'dog', 'likes', 'food']. charAt() is a function you call on a string, not array
Byron Lagrone
@byronic
Oct 26 2015 18:41
arrays do not have a .charAt(index) function (what would it call?). However, if you store the array in a variable, i.e. var myStringArray = str.split(' '); you can access the individual strings within the resultant array with myStringArray[0], myStringArray[1], etc -- and each of those will have access to the .charAt(0) function
Jason
@Skiippa
Oct 26 2015 18:41
So i would have to make the substring their own strings for charAt to work?
Byron Lagrone
@byronic
Oct 26 2015 18:41

@Skiippa You don't have a substring, you have an array of strings ;)
@thedigitalmonk
Oct 26 2015 18:41
That says a lot actually. It means the issue is with that particular line. Now why don’t you try and unchain it and do it one step at a time and see what happens when you call each function? Use console.log after each step you are not sure of the output. You’ll get a clearer error in your console. Once you fix it than you chain it up and make it look pretty. @Skiippa
h4r1m4u
@h4r1m4u
Oct 26 2015 18:41
you cannot call a string function on an array of strings. but you can iterate over the array elements (individual strings) and apply the charAt() function on them individually. *hint, hint

}

palindrome("eye");
Its working for all the scenarios but failing for 1
This error is being shown: palindrome("1 eye for of 1 eye.") should return false.
@thedigitalmonk
Oct 26 2015 18:44

@Skiippa here’s what I mean -

var splitString = str.split(‘ ‘);
console.log(splitString);

Now when you will try to do .charAt(0) on this you will get a clearer error on why it won’t work. Even before that you would have noticed that the splitString is an array and if you remembered from the previous challenges charAt() is a string method.

Then apply the next method and so on…

Step by step first man. You’ll learn a lot that way.

h4r1m4u
@h4r1m4u
Oct 26 2015 18:54
@yfarkash usually you would use map if you want to manipulate the array elements in some way (map returns a new array with elements from the original array after you applied the function on them). in this case, you don't need to manipulate the strings in any way. you just need to find the longest one
Yoav Farkash
@yfarkash
Oct 26 2015 18:56
@h4r1m4u yes, I was just hoping to practice the use of the .map function and create a new array with the lengths of the words in it, and then find the largest number in this array, just to practice.
but I cant seem to be able to do it, I dont know how to call the string.length function on each cell in the array....
This is what I tried: lengthsArray = array.map(str.length());
@SaintPeter
Oct 26 2015 18:57
@yfarkash .reduce would be better in this case because it returns a single value for an array.
@yfarkash That won't quite work. You would need:
lengthsArray = array.map(function(item) { return item.length(); });
Yoav Farkash
@yfarkash
Oct 26 2015 18:58

@h4r1m4u thank you, that works perfectly. I guess what is confusing to me is knowing which kind of functions I can just write directly as the .map first argument and which ones I need to write myself like your example did.

nop
You should add a <i class="fa fa-trash"></i> within your delete button element.
You should add a <i class="fa fa-info-circle"></i> within your info button element.
Make sure each of your i elements has a closing tag and <i class="fa fa-thumbs-up"></i> is in your like button element.

So, I used the .map to get my array of numbers, each is the length of the word in the array. Now I want to use .reduce to get the largest numbers. here is my code:

longestWord = lengthsArray.reduce(function(previousValue, currentValue, index, array) {
if currentValue > previousValue {
return currentValue;
} else {
return previousValue;
}

}
);

@yfarkash just add parentheses around the if condition:

@yfarkash Nope - they are functionally identical. If you look on the MDN site for the "polyfill" you will see that they have for loops inside
@yfarkash They just generally make code easier to read and (sometimes) to write

@SaintPeter awesome, very elegant. I do find it hard to read this kind of code though. I lreaned coding first some 20 yeara ago, before this extensive use of object-oriented programming, and this nested-style of functions.
@SaintPeter it takes me a while to decipher what each function does, and then trace it (mentaly) to where the output goes to, etc.
@SaintPeter
Oct 26 2015 19:32
@yfarkash Oh, yeah, me too. Functional Programming has been my biggest challenge in FCC. Kinda blew my mind at first, but once I "got it", I went back and redid a bunch of Bonfires to cement it. Now I kinda speak it naturally.
