maybe not :)
depends which way you want to do the match
one of those args is a lot longer ... be careful
arg1 is actually an array

now i was trying just a simple cicle
for (var i=0....)
for(var z in collection[i]){
console.log(collection[0].z);
}
since var z was giving me 'first' and last too
i tough i could access the values like this

Aug 04 2015 00:02
in the end i think collection.filter is all you need
no nesting
you're confused because trying to match with the nesting inside collection
i think source is better to use as the matchin item
and then just filter collection against that
anyway i think thats giving away too much
log your arguments coming in, that may clarify

to make the filter you always need a function? or can you make it without one?

Hi, everybody. I'm working on the bonfire Exact Change at
http://www.freecodecamp.com/challenges/bonfire-exact-change.
My solution below returns correct change sorted from highest
to lowest. However, it does not pass two of the tests. I'd
appreciate it if someone would tell me what is expected from
the tests and what the correct responses should be.

Here are the tests that are failing:

assert.deepEqual(drawer(19.50, 20.00, [['PENNY', 1.01], ['NICKEL', 2.05], ['DIME', 3.10], ['QUARTER', 4.25], ['ONE', 90.00], ['FIVE', 55.00], ['TEN', 20.00], ['TWENTY', 60.00], ['ONE HUNDRED', 100.00]]), [['QUARTER', 0.50]], 'return correct change');return correct change: expected [ 'QUARTER', 0.5 ] to deeply equal [ [ 'QUARTER', 0.5 ] ]
assert.deepEqual(drawer(3.26, 100.00, [['PENNY', 1.01], ['NICKEL', 2.05], ['DIME', 3.10], ['QUARTER', 4.25], ['ONE', 90.00], ['FIVE', 55.00], ['TEN', 20.00], ['TWENTY', 60.00], ['ONE HUNDRED', 100.00]]), [['TWENTY', 60.00], ['TEN', 20.00], ['FIVE', 15], ['ONE', 1], ['QUARTER', 0.50], ['DIME', 0.20], ['PENNY', 0.04] ], 'return correct change with multiple coins and bills');return correct change with multiple coins and bills: expected [ Array(7) ] to deeply equal [ Array(7) ]

Hey guys, does anyone know why this is returning empty brackets?
function slasher(arr, howMany) {

var array = [];

//If howMany is less than 1, return the original array because nothing is being cut
if (howMany < 1) {
return arr;
}

if (arr.length > howMany) {
var splicedArray = array.splice(howMany, arr.length);
array.push(splicedArray);
}

return array;
}

slasher([1, 2, 3], 2);
I have two green checkmarks now, but I have one error and I think it's related to the empty brackets
Also still have no idea why my code is purple and white

I still don't understand why I keep getting error messages when I attempt to get information from an API. Is there a difference between .getJSON, .get, .ajax? And why do we need to add ?callback=? to some. Also I'm getting an error message now when calling to https://en.wikipedia.org/w/api.php?action=query&titles=Main%20Page&prop=revisions&rvprop=content&format=json?callback=?. It says refused to execute script because it's MIME type (text/html) is not executable and strict MIME type checking is enabled. So does that mean the data is not JSON format and I need to try another way to get it?
Matt Everson
@matteverson
Aug 04 2015 02:20
@darrell1226 callback=? is special. jQuery is designed to replace that ? with a function it generates to return the result as an object. Otherwise, and here's the key for you - there should only be one ? in a URL, to indicate the end of the URL and the start of the querystring.

Grace @dogbot101 Aug 04 2015 02:55 Regardless, I agree with @dting . You might want to remove your .sort() . I was using your console.log to see what was wrong. It looks like it is returning the items in the wrong order for the last test Kolloom @Kolloom Aug 04 2015 02:55 @dting I don't know if that's a bug at all, but it does works, thanks Jalk65 @Jalk65 Aug 04 2015 02:55 @Rafase282 the first if checks to see if the player hit, if he did then it acknowledges the hit, prints a congrats message and checks total damage Kolloom @Kolloom Aug 04 2015 02:56 so the output should be in exact order? @dogbot101 that's not mentioned in the description of the bonfire at all Alfredo J Moreno @Junmr4 Aug 04 2015 02:57 am i heading in the right direction CamperBot @camperbot Aug 04 2015 02:57 type bonfire name to get some info on that bonfire here Grace @dogbot101 Aug 04 2015 02:57 @Kolloom The difference between an empty array and ['snuffleupagus', 'cookie monster', 'elmo'], is ['snuffleupagus', 'cookie monster', 'elmo']. Yes, it seems order does matter for it to pass.

I've found it to be helpful. Matt Everson @matteverson Aug 04 2015 02:59 @darrell1226 $.getJSON('https://en.wikipedia.org/w/api.php?action=query&titles=Main%20Page&prop=revisions&rvprop=content&format=json&callback=?', function(data){

Kolloom @Kolloom Aug 04 2015 03:07 @Daynewr im struggling with that bonfire too gazzer82 @gazzer82 Aug 04 2015 03:07 I have all the test cases returning correct, other than the first one "expected 3 to deeply equal 6" Matt Everson @matteverson Aug 04 2015 03:07 @Daynewr In any recursive function you need two branches. One returns right away when it shouldn't recurse anymore, and the other is the meat of what you want the function to do, ending with a return steamroller(stuff) gazzer82 @gazzer82 Aug 04 2015 03:08 Which i don't understand as the object only has firstName, lastName and fullName as attributes. Making three not six? Nic Galluzzo @ngalluzzo Aug 04 2015 03:08 you need 3 gets and 3 sets setFirstName, getFirstName gazzer82 @gazzer82 Aug 04 2015 03:09 Hi @ngalluzzo that i have. Darrell Wong @darrell1226 Aug 04 2015 03:09 @matteverson thanks. gazzer82 @gazzer82 Aug 04 2015 03:09 three sets and three gets, all those test cases are passing? Grace @dogbot101 Aug 04 2015 03:09 Also, @Junmr4 , it might help to think about two scenarios, if the string length is less than or equal to num, and another scenario if the string length is too long, and you need to shorten the string and add "..." Nic Galluzzo @ngalluzzo Aug 04 2015 03:09 you may have 3 properties and 3 methods post your code? gazzer82 @gazzer82 Aug 04 2015 03:10 Here's my code This message was deleted This message was deleted Matt Everson @matteverson Aug 04 2015 03:10 @Daynewr In steamroller, the ending condition is that the item is no longer an array. Which is good, because if you want to use reduce() in the alternate branch, then that will only work on an array ;) gazzer82 @gazzer82 Aug 04 2015 03:10 var Person = function(firstAndLast) { this.privateFullName = firstAndLast; var names = firstAndLast.split(" "); this.privateFirstName = names[0]; this.privateLastName = names[1]; }; Person.prototype.getFullName = function(){ return this.privateFullName; }; Person.prototype.getFirstName = function(){ return this.privateFirstName; }; Person.prototype.getLastName = function(){ return this.privateLastName; }; Person.prototype.setFullName = function(name){ this.privateFullName = name; }; Person.prototype.setFirstName = function(name){ this.privateFirstName = name; }; Person.prototype.setLastName = function(name){ this.privateLastName = name; }; var bob = new Person('Bob Ross'); bob.getFullName(); @ngalluzzo Nic Galluzzo @ngalluzzo Aug 04 2015 03:11 you can’t use Prototypes @gazzer82 you need to use the object constructor @gazzer82 gazzer82 @gazzer82 Aug 04 2015 03:12 Ah that makes sense, as the private var's made no sense with Object.Prototype. Thanks CamperBot @camperbot Aug 04 2015 03:12 gazzer82 sends brownie points to @ :sparkles: :thumbsup: :sparkles: Logan Tegman @ltegman Aug 04 2015 03:13 @gazzer82 You want to be mindful about the fact that your functions for setting the first and last name aren’t updating the fullname and the setfullname isn’t update the first and last. Best to just keep one record (either the full name or separate first and last) to remove that duplication and possiblity for conflicts. Matt Everson @matteverson Aug 04 2015 03:14 @Daynewr What you want that reduce to return is a single array containing all the items. So when you call steamroller() recursively it will give you a single array. So...we need a function that concatenates elements of one array to another. (The previous items in the reduce to the results of a recursive steamroller call) Dayne Wright @daynewright Aug 04 2015 03:15 @so you need two functions ultimately? Matt Everson @matteverson Aug 04 2015 03:16 @Daynewr Yes, but it's built in. gazzer82 @gazzer82 Aug 04 2015 03:18 @ltegman yes i initially just had the string being split and was just storing the firstName and lastName separately, just got to that point trying to work out why the tests weren't completing. @ngalluzzo and @ltegman this is what i have now. var Person = function(firstAndLast) { var names = firstAndLast.split(" "); var firstName = names[0]; var lastName = names[1]; this.getFullName = function(){ return firstName + ' ' + lastName; }; this.getLastName = function(){ return lastName; }; this.getFirstName = function(){ return firstName; }; this.setFullName = function(name){ names = name.split(" "); firstName = names[0]; lastName = names[1]; }; this.setFirstName = function(name){ firstName = name; }; this.setLastName = function(name){ lastName = name; }; }; var bob = new Person('Bob Ross'); bob.getFullName(); Should i move the methods into an external object and use it to extend Person? Nic Galluzzo @ngalluzzo Aug 04 2015 03:23 your variables don’t match for setFullName Logan Tegman @ltegman Aug 04 2015 03:23 @gazzer82 I don’t think so. Looks good -- although again, best practice would be to remove the variable duplication. Nic Galluzzo @ngalluzzo Aug 04 2015 03:23 @gazzer82 your argument is name but you’re splitting names gazzer82 @gazzer82 Aug 04 2015 03:26 @ngalluzzo sorry wrong version, this is my final version, how dos this look? var Person = function(firstAndLast) { var names = firstAndLast.split(" "); var firstName = names[0]; var lastName = names[1]; this.getFullName = function(){ return firstName + ' ' + lastName; }; this.getLastName = function(){ return lastName; }; this.getFirstName = function(){ return firstName; }; this.setFullName = function(name){ names = name.split(" "); firstName = names[0]; lastName = names[1]; }; this.setFirstName = function(name){ firstName = name; }; this.setLastName = function(name){ lastName = name; }; }; var bob = new Person('Bob Ross'); console.log(bob.getLastName()); Liz Rezes @queenlizo Aug 04 2015 03:26 I'm doing the bonfire Chunky Monkey.

Darrell Wong @darrell1226 Aug 04 2015 03:28 I'm having trouble with Bonfire: No repeats please. Running the code says "aab" has two permutations. But I calculate three: aab, aba, and baa. I'm not understanding this. gazzer82 @gazzer82 Aug 04 2015 03:28 @ltegman see above, does that fix the variable duplication? Liz Rezes @queenlizo Aug 04 2015 03:29 @Kolloom Ha! That I don't know. Darrell Wong @darrell1226 Aug 04 2015 03:29 Nevermind, I read the instructions wrong. Logan Tegman @ltegman Aug 04 2015 03:29 @gazzer82 You solved the problem of them getting out of sync with eachother, but you’re still storing the full name in two different places (separate and full) which is something you want to avoid. You never want to store the same data in more than one place. Adam @stwaldo Aug 04 2015 03:29 @queenlizo are you using slice correctly? I think the second argument is the index of the last chunk, not the size of the slice @queenlizo So when you have a static argument like arr. slice(i, 2) it’s always going to slice to the element at index 2 gazzer82 @gazzer82 Aug 04 2015 03:30 @ltegman do you mean the names var at the beginning of the function? How would you go about accessing the first and last name of the string sent without storing it in a var? Should i just make the call split twice? Liz Rezes @queenlizo Aug 04 2015 03:31 @stwaldo When I change it to myArray.push(size);, it returns this: myArray.push(size); wooops Argh. Can't copy and paste it. Suffice to say that it doesn't work. :( Adam @stwaldo Aug 04 2015 03:32 @queenlizo I think you’re fine using slice, you just have to update the second argument so that it moves with your counter, like …slice(i, i+size) Logan Tegman @ltegman Aug 04 2015 03:32 @gazzer82 You could either only store the full name and split it whenever you need to set or get a single name, or store the individuals and concatenate or split when you need to get or set the full name. Liz Rezes @queenlizo Aug 04 2015 03:32 @stwaldo Ah. I used that argument before. Let me try again gazzer82 @gazzer82 Aug 04 2015 03:32 @ltegman so changing it to something like this: var Person = function(firstAndLast) { //var names = firstAndLast.split(" "); var firstName = firstAndLast.split(" ")[0]; var lastName = firstAndLast.split(" ")[1]; this.getFullName = function(){ return firstName + ' ' + lastName; }; this.getLastName = function(){ return lastName; }; this.getFirstName = function(){ return firstName; }; this.setFullName = function(name){ firstName = name.split(" ")[0]; lastName = name.split(" ")[1]; }; this.setFirstName = function(name){ firstName = name; }; this.setLastName = function(name){ lastName = name; }; }; var bob = new Person('Bob Ross'); console.log(bob.getLastName()); Liz Rezes @queenlizo Aug 04 2015 03:34 @stwaldo Nope. It's ok. I think that I'm going to go do something else for a while to clear my brain. Thanks for your help! Logan Tegman @ltegman Aug 04 2015 03:35 @gazzer82 Yup — looks great. Adam @stwaldo Aug 04 2015 03:35 @queenlizo np! Good luck :-) gazzer82 @gazzer82 Aug 04 2015 03:35 Great, thanks for the help and advice, really appreciated! Logan Tegman @ltegman Aug 04 2015 03:36 @gazzer82 No problem :smile: gazzer82 @gazzer82 Aug 04 2015 03:37 @ltegman I guess in theory i should also check that when i get a fullName string it can actually be split before trying to set the firstName and lastName, or is that unneeded as they will just get set to undefined? if(firstAndLast.split(" ").length === 2) Logan Tegman @ltegman Aug 04 2015 03:38 @gazzer82 Up to you — I don’t think any of the bonfires require input checking in order to pass the tests, but stuff like that is a really good thought process to have for when you start making apps in the wild and definitely doesn’t hurt to start practicing now. gazzer82 @gazzer82 Aug 04 2015 03:39 Ok cool, thanks. Out of interest @ltegman are you doing FreeCodeCamp? Logan Tegman @ltegman Aug 04 2015 03:41 @gazzer82 Yup — I’ve been programming on and off for a couple years now, but I want to finally turn it into a career, so I’m hoping this can help me get there. I’m halfway through the ziplines right now. ninjatron @ninjatron Aug 04 2015 03:42 i am not sure i understand Bonfire: Arguments Optional gazzer82 @gazzer82 Aug 04 2015 03:43 @ltegman Ditto, but i've been almost exclusively Objective C, so this is a bit of a change. Similar in wanting to make a change, kinda now or never time really. Thinking i might go and do a residential bootcamp course afterwards if all goes to plan, maybe even Hack Reactor if they let me in. How long did it take you to get to the Ziplines? Finally decided to see if i can make some money from my Hobby, and see how i measure up to everyone else. Logan Tegman @ltegman Aug 04 2015 03:45 @gazzer82 Oh yeah, that sounds like quite a change. I came from C# primarily, but I had done web stuff in college. I’m planning to do the same thing with an in-person bootcamp early next year. There’s one near me in Seattle called Code Fellows that seems to have good reviews, so I’m excited for that! I think it took me about 11 days to get to the ziplines. I used to get to do some dev stuff at my job, but as time has gone on that has moved to people who were actually hired to be devs, so I’m anxious to move on and make software something that is my full time gig! gazzer82 @gazzer82 Aug 04 2015 03:50 Ah ok, hadn't heard of Code Fellows but i'll check them out, are they Javascript or Ruby orientated? My job has nothing really to do with this at all, but i have done a decent amount of iOS OS X stuff for people on the side. Had to do a full stack setup a few months ago and used Meteor, but realised that if i was gong to do this i really needed to learn Javascript first. If i was going to spend that much money on a bootcamp i wanted to make sure i was going in as up to speed as i could be, and saw this on Product Hunt and it looked ideal! CamperBot @camperbot Aug 04 2015 03:50 we have a meteor channel here: camperbot/meteorJS Logan Tegman @ltegman Aug 04 2015 03:53 @gazzer82 Yeah, same here. I want to make sure I’m prepped to excel if I’m paying for something. Code Fellows does a bunch of different stacks, Ruby, JS, Swift, Python, and Front-End. That’s fun you’ve got a chance to dive into it on the side. How was your experience with clients? I did a website for a client a while back and absolutely hated the experience of working with them.

Most of the stuff i've done has been for tech savvy friends who own companies so not too bad. But my day to day involves dealing with clients all the time, in quite high stress environments, often being shouted at, so that bit i find quite easy :) ninjatron @ninjatron Aug 04 2015 04:02 bonfire arguments optional CamperBot @camperbot Aug 04 2015 04:02 ## :fire:Bonfire: Arguments Optional :link: function add() { return false; } add(2,3); Create a function that sums two arguments together.

I think you’ll only really get it once you start applying it more and more. If you find yourself getting overwhelmed or confused by loops and arrays in the later stuff you can always go back again. Kolloom @Kolloom Aug 04 2015 04:03 @sholdgrafer i'd say move on, there's no shortage of loops and arrays in the later courses, they have a bunch of review sections too later down the line (assume you are talking about codecademy) ninjatron @ninjatron Aug 04 2015 04:03 bonfire info CamperBot @camperbot Aug 04 2015 04:03 ## :fire:Bonfire: Arguments Optional :link: function add() { return false; } add(2,3); Create a function that sums two arguments together.

Also check that FCC ID matches githubID! ninjatron @ninjatron Aug 04 2015 06:10 @Woolwit why do you bother checking if one is an empty array? just create an empty array and push unique values to that array Woolwit @Woolwit Aug 04 2015 06:15 Yes, I could start near the beginning again. I'm a few hours into the Diff Two Arrays Bonfire, and my solution passed every test but the one with the empty array. But now I'm curious... Why doesn't this make it to the console.log? function diff(arr1, arr2) { if (arr1 == []) { console.log('Kick me hard.'); } } diff([], ['snuffleupagus', 'cookie monster']) ninjatron @ninjatron Aug 04 2015 06:19 i don't know if it's the case with JS as well but in C++ an array is a pointer so it just points to a specific location in memory therefore you can't compare arrays the way you do so if you wanted to compare 2 arrays you would have to check each index of both arrays Woolwit @Woolwit Aug 04 2015 06:21 Thanks again @ninjatron I will explore that.

Logan Tegman @ltegman Aug 04 2015 06:24 @LegitStudent In a symmetric difference of 3 anything in all three is included in the set. I think of it as the first two fives cancelling eachother out (like they would in a set of two) which leaves the last one in the set with nothing to cancel it. Woolwit @Woolwit Aug 04 2015 06:29 Thanks @ltegman I will try that.

Aug 04 2015 08:33
from what I understand so far, is some sort of way to store information in a text file.
kind of like javascript object syntax, but only to store key-value pairs in a simple file
I don't understand how API's make use of it, or what I'm supposed to do with them yet, though... :fearful:
Omar
@oab00
Aug 04 2015 08:35
you send a $.getJSON to an API then they send you back a .json file that contains the quote you need Alexandro Perez @AlexandroPerez Aug 04 2015 08:35 BTW, it took me a long time to figure out how to make the twitter button work for each randomly generated quote. Omar @oab00 Aug 04 2015 08:35 after that you show the quote to the user and send $.getJSON again when the user presses for new quote
Alexandro Perez
@AlexandroPerez
Aug 04 2015 08:37
It seems that taking that approach from the beginning would've saved me a lot of time.
I'll try that approach now.
Omar
@oab00
Aug 04 2015 08:38
@AlexandroPerez for example the website http://quotesondesign.com/ has an API button on the bottom right
if you go to this URL using a browser it returns a JSON with a random quote:
http://quotesondesign.com/wp-json/posts?filter[orderby]=rand&filter[posts_per_page]=1
Alexandro Perez
@AlexandroPerez
Aug 04 2015 08:38
Like using qoutes from here:

@Honno the map is organised from top to bottom it shouldn't make u jump from a point to point .. but you can of course skip things if you feel like you already know them
if it made u jump then it's probably a bug somewhere

@Stiino0 you should take out that comparison from the indexOf function
if (first.indexOf(second[i] === -1)) to if (first.indexOf(second[i]) === -1)
this way you get the actual index if it's found :)

@sojelee for the add(2, '3') case it's because you're doing
arg1=parseInt(arguments[1]); before checking if the value is a number
@sojelee you should put the isNaN(arg#) checking before parseInt(arg#)
actually.. isNaN seems ot be acting weird maybe you should replace it with typeof instead
console.log(typeof arguments[1] !== 'number');

however, I turned that off and wanted to make sure my code was complete, but it doesn't work for some reason?

Good morning, everybody. I'm working on the bonfire, "Exact Change",
http://www.freecodecamp.com/challenges/bonfire-exact-change.
I posted this question last night but it did not get any traction.

My solution below returns correct change sorted from highest
to lowest. However, it does not pass two of the tests. I'd
appreciate it if someone could help me understand what
is expected from the tests and what the correct responses should be.

Here are the tests that are failing:

assert.deepEqual(drawer(19.50, 20.00, [['PENNY', 1.01], ['NICKEL', 2.05], ['DIME', 3.10], ['QUARTER', 4.25], ['ONE', 90.00], ['FIVE', 55.00], ['TEN', 20.00], ['TWENTY', 60.00], ['ONE HUNDRED', 100.00]]), [['QUARTER', 0.50]], 'return correct change');return correct change: expected [ 'QUARTER', 0.5 ] to deeply equal [ [ 'QUARTER', 0.5 ] ]
assert.deepEqual(drawer(3.26, 100.00, [['PENNY', 1.01], ['NICKEL', 2.05], ['DIME', 3.10], ['QUARTER', 4.25], ['ONE', 90.00], ['FIVE', 55.00], ['TEN', 20.00], ['TWENTY', 60.00], ['ONE HUNDRED', 100.00]]), [['TWENTY', 60.00], ['TEN', 20.00], ['FIVE', 15], ['ONE', 1], ['QUARTER', 0.50], ['DIME', 0.20], ['PENNY', 0.04] ], 'return correct change with multiple coins and bills');return correct change with multiple coins and bills: expected [ Array(7) ] to deeply equal [ Array(7) ]

Here is my code:
and here is a link to repl.it to see a working model: http://repl.it/BACR/2


var reg = {
total: function(cid){
var cashAmts = [];
cid.forEach(function(v){
cashAmts.push(v[1]);
});
var sum = cashAmts.reduce(function(a, b){return a + b;
}).toFixed(2);
return +sum;
},

denomMap:  [
100, 'ONE HUNDRED', 20, 'TWENTY', 10, 'TEN', 5, 'FIVE', 1, 'ONE', 0.25, 'QUARTER', 0.1, 'DIME', 0.05, 'NICKEL', 0.01, "PENNY"
],

combine: [],

display: function(change) {
var num = change;
var value = '';
for (var i = 0; change > 0 && i < this.denomMap.length; i += 2) {
while (change >= this.denomMap[i]) {
change += this.denomMap[i + 1];
change = change.replace(/\d+/g, "");
change = change.replace(/\./g, "");
value += this.denomMap[i];
var div = Math.floor(num/+value) * this.denomMap[i];
var temp = [change, div];
this.combine.push(temp);

}
}

return this.combine;

};

The same error as last night @davisec52
The reg.display method seems broken since the second test receives an array consisting of 15 elements
while there are only 9 bills/coins available
your for loop is made to access an array with indices 0, 2, 4, ... but the actual array has indices 100, 20, 10, ...
You also check if change >= denomMap[i] so you compare a number with a string which leads to nonsense, no?

@labiej Ok, thank you. The solution appears to sort change from highest to lowest in correct amounts. The array includes string and number pairings for denominations and amounts.
@labiej The idea with the loops is that depending on the iteration, denomMap[i] will be a number.

Tristanto
@rustyworks
Aug 04 2015 12:32
Here is the flaw in your code:
1. You should swap first else if with second else if
So you should check if arguments.length first instead checking it's type
Or ...
You can check it one by one first
2 You should check the value of x by using typeof just like your code

return undefined;
}

else if (arguments.length === 1) {

} else {
return arguments[0] + x;
}
};

}

else if (typeof arguments[0] !== 'number' || typeof arguments[1] !== 'number') {

Hi all, not sure what is going wrong here: I am checking for a palindrome, and according to my console.log tests, this is working fine, but the tests do not pass.

function palindrome(str) {
// Good luck!
var lowerCaseStr = String.toLowerCase(str);
var lowercaseNoPuntuation = lowerCaseStr.replace(/[\W_]+/g,"");
var array = lowercaseNoPuntuation.split('');
console.log("lowercaseNoPuntuation: " + lowercaseNoPuntuation);
array.reverse();
var reversedString = array.join('');
console.log("reversed: " + reversedString);
if (str === reversedString)
{
return true;
}
return false;
}

Watsup dudes and dudettes?
I wanna run something by you guys from Eloquent JavaScript
var input = "A string with 3 numbers in it... 42 and 88.";
var number = /\b(\d+)\b/g;
var match;
while (match = number.exec(input))
console.log("Found", match[1], "at", match.index);
// → Found 3 at 14
//   Found 42 at 33
//   Found 88 at 40
This makes use of the fact that the value of an assignment expression (=) is the assigned value. So by using match = number.exec(input) as the condition in the while statement, we perform the match at the start of each iteration, save its result in a variable, and stop looping when no moe matches are found.
I dont get why this works
I thought the expression had to eval to true or false

@CPatel217 you got one regex expression right? that looks for a digit
next, the variable, and in the while cicle, you start searching for a match in that regex.
If it's found, it logs, and then continues from the index you previously had. meaning it will not get the same numbers twice

@CPatel217 not quite
you should pass to while boolean value

if you pass to while something else than boolean value, javascript will try to make sens of that

can any one suggest what might be wrong with this
function replace(str, before, after) {
var arr = str.split(" ");
var i;
for(i=0;i<arr.length;i++){
var match =  arr[i];
if(match === before){
arr.splice(i,1,after);
}
}
var ret = arr.join(' ');
return ret;
}

@ShaklinSyed I think you are replacing only one character of the original string.
@ShaklinSyed Which tests does it pass?
Shaklin
@ShaklinSyed
Aug 04 2015 13:32
expect(replace("Let us go to the store", "store", "mall")).to.equal("Let us go to the mall");
expect(replace("This has a spellngi error", "spellngi", "spelling")).to.equal("This has a spelling error");
these both work

@CPatel217 When exec fails to find mach in provided string, it returns null. null is evaluated to false. But null is a value, there is always a value - its just falsy value
Shaklin

Aug 04 2015 13:34
@Dadsaster the first argument is the index where to start and second is the number of elements to remove and third are the elements to be added if i am right

matejhegedus
@matejhegedus
Aug 04 2015 13:36
@ShaklinSyed I think the problem is that you're not preserving the case from the original string. When the replaced word is capitalised, the new word should be too.
Oliver
Aug 04 2015 13:36
@ShaklinSyed I know - your code works on my machine - which case fails?

@matejhegedus that is what i thought
@Dadsaster replace("He is Sleeping on the couch", "Sleeping", "sitting")
matejhegedus
@matejhegedus
Aug 04 2015 13:37
@ShaklinSyed You need to check if the first character from the replaced word is capitalised.

@flota113 I've got it all passing except the last test. I don't get how providing a single array is a valid test when symmetric difference seems to require something to compare against...Can you explain?
flota113
@flota113
Aug 04 2015 13:56
give me a sec - opening the challenge to see the test ;)
actually You're right - I mean the description explicitly says that Your function should take two or more arrays
but for now You can easily fix it(as I did)

Hi, all! I'm doing the Chunky Monkey bonfire, and can't get this to work. It should break up the array into 2 subarrays with 2 numbers in each one.
function chunk(arr, size) {
// Break it up.
var myArray = [];
for (var i=0; i < arr.length; i++) {
myArray.push(arr.slice(i, i+size));
}

if (arr.length) {
myArray.push(arr);
}
return myArray;
}

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

@Jorgixhallo
Aug 04 2015 14:14
@queenlizo just to begin:
think about this cicle for (var i=0; i < arr.length; i++) {
if you have length 4, you want it to push 4 times?
also, why are you pushing twice to myArray? that if (arr.length) { will always evaluate true I gess
Liz Rezes
@queenlizo
Aug 04 2015 14:17
@Jorgixhallo I want the final result to be 2 sub arrays of 2 numbers. This code is the closest I've been to it
Moisés Man
@moigithub
Aug 04 2015 14:17
the question is correct but still missing something....
on the example.. it passing 2, as size.. to make groups of 2 elements
so... if u have ([1,2,3,4],2 )
the result should be [1,2], [3,4] (2 groups)
so u only need to iterate 2 times..
matejhegedus
@matejhegedus
Aug 04 2015 14:17
@queenlizo for (var i=0; i < arr.length; i++) should be for (var i=0; i < arr.length; i += size) I think
Paul Soper
@pdsoper
Aug 04 2015 14:17
@LCBecker It looks like you need to increase your col-sm-offset-2
L. Becker
@LCBecker
Aug 04 2015 14:18
@pdsoper For which div?
Liz Rezes
@queenlizo
Aug 04 2015 14:18
@matejhegedus That's closer! It spit out 2 sub arrays, and then the whole array again
@moigithub Thanks. Let me fiddle with it some more.
Paul Soper
@pdsoper
Aug 04 2015 14:19
@LCBecker For the ones containing F and C. Try col-ms-offset-9
Jorge Almeida
@Jorgixhallo
Aug 04 2015 14:19
@queenlizo with your code i'm getting 5 sub arrays if i'm not wrong. @matejhegedus Don't just give the answer like that xD
Moisés Man
@moigithub
Aug 04 2015 14:19
@queenlizo slice..copy part of an array.. but it DO NOT modify the original one...
matejhegedus
@matejhegedus
Aug 04 2015 14:20
@queenlizo Since you are not removing elements from the array, this part will push the whole array again into the result
if (arr.length) {
myArray.push(arr);
}
L. Becker
@LCBecker
Aug 04 2015 14:20
@pdsoper That offset is to put the F and C in the middle of the circle. It doesn't move the small circle to the right of the big circle.
Moisés Man
@moigithub
Aug 04 2015 14:20
so this..
if (arr.length) {
still checkign the full size origininal array
Paul Soper
@pdsoper
Aug 04 2015 14:21
@LCBecker Sorry. Try adding col-sm-offset-8 to the circle div around them
Liz Rezes
@queenlizo
Aug 04 2015 14:21
@matejhegedus if I take that out, it says that I have an illegal return statement
I got it! I changed the if statement to this:
 if (arr.length) {
myArray.push();

@LCBecker By the way, there are specific help groups for Ziplines (and Basejumps)
Moisés Man
@moigithub
Aug 04 2015 14:22
@queenlizo
if u have this [1,2,3,4,5], 2
ur groups (of 2 elements) should be....
[1,2]
[3,4]
[5] <-- include leftover

@LCBecker I'm no expert in Bootstrap, so I had no idea you could use columns in such a way.

Anyway, what first come to mind with the approach you are trying to take is to use relative positioning to a parent element. That way no mater where the parent element is at, the child will be at a relative position of its parent.

Take a look at this stack-overflow question:

Aug 04 2015 14:28
To be honest I thought bootstrap layout system was more suited for layouts that don't require such complex positions, but I guess that's because I haven't try to do it myself.
