Moisés Man
@moigithub
Aug 27 2016 00:00 UTC
@crazymaster49 u need to create a math expression and assign it to a variable...
javascript will calculate whatever result is
ie: total = 2+5;
crazymaster49
@crazymaster49
Aug 27 2016 00:01 UTC
ok thank you all, but how do you use finding a remainder in JavaScript? if that is not correct.
Moisés Man
@moigithub
Aug 27 2016 00:02 UTC
using the remainder operator %
+ adition operator total = 2 + 5
/ division operator total = 2 / 5
* multiplication operator... total = 2 * 5
soo.. how u would find remanding using the remainder operator ??? %
Egoscio
@Egoscio
Aug 27 2016 00:02 UTC
a.k.a. modulo
crazymaster49
@crazymaster49
Aug 27 2016 00:03 UTC
Can you give me an example @moigithub in code of how this is used?
Joseph Parkton
@hippybear
Aug 27 2016 00:03 UTC
@Egoscio I think there is a difference
3 % 9 === 0

@crazymaster49 you can also do this in your devtools and see it in action
Moisés Man

Aug 27 2016 00:05 UTC
of course u need to use whatever variable name /values the instruction tells u to do.. @crazymaster49

@Egoscio right??
A strange step from python to %
Egoscio
@Egoscio
Aug 27 2016 00:07 UTC
AH I was right about one thing, the main difference is the signs
"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

@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

BrianR
@brianrudloff
Aug 27 2016 00:28 UTC
hi
Egoscio
@Egoscio
Aug 27 2016 00:28 UTC
Here's the doc page
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
BrianR
@brianrudloff
Aug 27 2016 00:30 UTC
hmm, cool. it's going to take me a while to absorb this
Egoscio
@Egoscio
Aug 27 2016 00:30 UTC
(note: the arguments array isn't really an array, so it doesn't conform to the standard Array protocol)
Joseph Parkton
@hippybear
Aug 27 2016 00:31 UTC
Thats more node logic than pure js but it still applies
you will encounter it more in node

@Egoscio
Aug 27 2016 00:31 UTC

Joseph Parkton

Well, arguments is a wannabe array, it's an object with numbered properties
but it doesn't have stuff like .reduce or forEach (IIRC)
Joseph Parkton
@hippybear
Aug 27 2016 00:32 UTC
arr = [{some: 1},{some: 3},{some: 33}]
an array of objs

Aug 27 2016 00:39 UTC
if string is "AA" u return [["A","T"],["A","T"]]
T is pair of A.. (check the instructions)

@hippybear An arguments "array" is something like:

it's not
var arguments = ['firstArg', 'SecondArg']
Joseph Parkton

Aug 27 2016 00:41 UTC
function doStuff(a,arr){} doStuff(1, 44) will now have an array of ["44"]

Aug 27 2016 00:41 UTC
@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'])

like this?
Moisés Man
@moigithub
Aug 27 2016 00:49 UTC
@Byzgig arr.indexOf(arr[i]) will return the same value of i .. also the other one.. will return j value
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 arr[0] + arr[0] --->>> if(arr[i] + arr[j] === arg){
u should NOT use the same element to make the sum calc
Om Agarwal
@om00webdeveloper
Aug 27 2016 00:50 UTC
oh ok @moigithub

function largestOfFour(arr) {
var finalarr = [];

is this what I am supposed to do? It's still outputting a empty array
Moisés Man
@moigithub
Aug 27 2016 00:52 UTC
@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
Om Agarwal
@om00webdeveloper
Aug 27 2016 00:52 UTC
yeah
thats why i used one loop in the first place
Moisés Man
@moigithub
Aug 27 2016 00:52 UTC
i seee 2 for instructions on ur code @OmAgarwal2002

@AshriSoft what do u mean
David Halls
@DavidHalls
Aug 27 2016 00:54 UTC
@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?
Moisés Man
@moigithub
Aug 27 2016 00:54 UTC
@OmAgarwal2002 what data type is j cuz j[i] is wrong
Om Agarwal
@om00webdeveloper
Aug 27 2016 00:54 UTC
@moigithub just an int
Walid Ashri
@walidashri
Aug 27 2016 00:55 UTC
@OmAgarwal2002 the second arg in apply is array I c j[i] which = nothing
Moisés Man
@moigithub
Aug 27 2016 00:55 UTC
@OmAgarwal2002 soo if j have a 0 value
and 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
Walid Ashri
@walidashri
Aug 27 2016 00:56 UTC
just use one loop and ref arr[i] instead of j[i] @OmAgarwal2002
Moisés Man
@moigithub
Aug 27 2016 00:57 UTC
@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..
David Halls
@DavidHalls
Aug 27 2016 00:58 UTC
@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

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
Cage Echarte
@CageEcharte
Aug 27 2016 01:08 UTC
@moigithub which val?
Moisés Man
@moigithub
Aug 27 2016 01:08 UTC
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 name
soo when u execute/call ur function like this orderMyLogic( 4 ); what do u think willl be the value of val

Write a function nextInLine which takes an array (arr) and a number (item) as arguments. Add the number to the end of the array, then remove the first element of array. The nextInLine function should then return the element that was removed.

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);

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.
err href attribute

@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.

Remove the a on the right side of the += sign
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);
});
Inspiration is the variable with the quote

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;
}

@Natto278 on the last if statement, the '===false' cancels out the .hasOwnProperty() statement, I think

@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"

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;
var percent = -0.005;
var t = this;
clearInterval(outInterval);
interval = setInterval(function(){
if(percent >= -0.1){
percent -= 0.005;
}
}, 10);
});
var percent = -0.1;
var t = this;
clearInterval(interval);
outInterval = setInterval(function(){
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

as far as I know, @jamesmillerho css only has on hover, and on active events
that means it'll do something while the mouse is on the button
but it doesn't handle a click
that's why you can do something like a dropdown list with pure css
but not a toggled menu like that

function rot13(str) {
//str = str.split('');
var rot13 = "";
for (var i = 0; i < str.length; i++){
if (90 >= str.charCodeAt(i) >= 65){
if (str.charCodeAt(i) < 78){
console.log(String.fromCharCode(str.charCodeAt(i)+13));
rot13 += String.fromCharCode(str.charCodeAt(i)+13);
} else {
var num = 90 - str.charCodeAt(i);
rot13 += String.fromCharCode(65+num);
}
} else {
rot13 += str[i];
}
}
return rot13;
}

// Change the inputs below to test

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

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

@Masd925 .hasOwnProperty only allows me to check the existance,not the value
Markus Kiili
@Masd925
Aug 27 2016 10:42 UTC
@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()

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 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
Markus Kiili
@Masd925
Aug 27 2016 11:05 UTC
@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.

@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.

@BKinahan There is serious scientific study on the subject of whether our universe is a computer simulation.

Hmm...maybe a black hole is really an OUROBOROS?

Brendan Kinahan
@BKinahan
Aug 27 2016 13:24 UTC
@Masd925 I would argue that you couldn't make any conclusions based on that, since a simulation crash would break causality
@dbeczuk you're not really using a prototype, you're just accessing the slice() method which is a property of the Array prototype

@dbeczuk [].slice() is shorter to write than Array.prototype.slice(). No difference otherwise.

@PrivateRoom5 The for .. in loop is not needed - as you are not using key. You cannot have two returns, use brackets with prop

@PrivateRoom5 Remove the first return and fix the second - you are only suppose to return the prop (as you are given the firstname)

so I can have as many console.log() as I want but just one return

@sjames1958gm nope I found that canvas ratio is fixed width = height *2 so if you change that ratio the content ratio will change to but thanks anyway

^proper way to do it
"When no width and height attributes are specified, the canvas will initially be 300 pixels wide and 150 pixels high."

@PrivateRoom5 Return leaves the function directly, so you cannot have a return followed by a return
Multiple returns in a function are allowed/used but need to be in different paths in the code (such as if () { return; } else { return; })

@BKinahan After some further reading some claim that Array.prototype.slice() is faster than [].slice() because [] is an instence of Array.
but I am not sure if that affects the performance on small collections of data.
and it might be relevant on large amounts of data
@Lieutenant4 [value];
Donatas
@Lieutenant4
Aug 27 2016 13:46 UTC
which one?
David Beczuk
@dbeczuk
Aug 27 2016 13:46 UTC
should be value , lose the []
and you have an else if after else.
Aug 27 2016 13:47 UTC
@Lieutenant4 - one thing that you can do is to group all of the actions when the value !== '' within one if block:
if ( value !== '' ) {
// do the things here if the value is not blank
} else {
// do the things here if the value is blank
}
David Beczuk
@dbeczuk
Aug 27 2016 13:48 UTC
else if never goes after an else. Else is the last action in an if else loop. and you have else .... else if .... else

@sunpeng897570 soo if u check ur loop..
it will ITERATE on all the contacts objects..
and compare each of those names.. vs the firstName u pass
soo IF the first contact match the name.. ur variable _type will be whatever contact property it have...
but on the NEXT check.. contact will NOT match.. soo it overwrite _type value
... ur code on each iteration will CHANGE _type value

Aug 27 2016 14:38 UTC
@TylerL-uxai - yes, the text that is already there is still expected to be there, the spelling (capitalization, etc., as they specify) is important. The testing code is looking for very specific things, and even though it might look correct to you, the testing code cannot be fooled... :) Use the testing results to help you, also - it tells you want it is looking for!

@PrivateRoom5 - you need to match the firstName in order to properly return the "No such property" status - your code does not properly do that check. In fact, you can eliminate the multiple for loops and put all of the testing and checking into the body of one for loop. (Keeping in mind that you have to be careful about the "No such contact" return...)
