I was wondering how to see our submitted answers to the challenges. I checked on my profile but only see links to my projects and some of the algo and data structures projects

@zebralight Go to https://www.freecodecamp.org/ Click on Curriculum in the top menu after logging in. There you can see a list of every challenge you've completed and the ones you still need to do. If you click on the completed one, you'll be taken to the challenge. There your answer should be present in the code
Zebralight
@zebralight
Jun 21 2018 01:35
@bjorno43 I had assumed that that would be the case, but I'm presented with the setup code with my implementation missing. I actually do prefer that my answer doesn't show up when I review challenges I've already completed, but I was also hoping to have the option of seeing my previously submitted code as well

@bjorno43 it's fun finding these weird idiosyncrasies in JS. i like figuring out the reasoning behind them
Claudio Restifo
@Marmiz
Jun 21 2018 02:42
@thekholm80 so please tell me why NaN !== NaN. Never really got that one.
Kyle Holm
@thekholm80
Jun 21 2018 02:42
ugh i knew this one
only because i ran into this somewhere in a project or something, and had to learn the wonder of isNaN()
MDN's pollyfill is kind of cool
var isNaN = function(value) {
    var n = Number(value);
    return n !== n;
};
Bjorn van de Peut
@bjorno43
Jun 21 2018 02:46
According to the IEEE 754 floating-point standard, comparison with NaN always returns an unordered result. That is, NaN is not equal to, greater than, or less than anything, including itself
Kyle Holm
@thekholm80
Jun 21 2018 02:47

i like this:

pragmatically speaking, though, two values of which you only know they're not numbers can't logically be the same thing.

Claudio Restifo
@Marmiz
Jun 21 2018 02:47
@thekholm80 that's because isNaN coerce the value to a number and then test if it's one. On the other hand Number.isNaN(val) will be true only if val is NaN
Bjorn van de Peut
@bjorno43
Jun 21 2018 02:48
So to make it simple: Comparison with NaN should always return false
Claudio Restifo
@Marmiz
Jun 21 2018 02:50

@bjorno43 @thekholm80 I always take it for granted. But never actually saw the reasoning for them. Like I know a NaN won't ever be equal to another NaN...

but why :)

probably has to do with imprecision and coercion
Kyle Holm
@thekholm80
Jun 21 2018 02:51
in python it's really easy to see the why behind these things - i've not found docs like that for js
every change to python gets tagged and posted for everyone to see
Claudio Restifo
@Marmiz
Jun 21 2018 02:52
kinda like since we cannot be sure of the exact value of this, and we actually have to coerce it to a different value to make it representable... let's say that it's unique. So won't ever be equal to anything else
Bjorn van de Peut
@bjorno43
Jun 21 2018 02:52
NaN always returns an unordered result = Each call for NaN returns something else
@Marmiz @thekholm80 Here you go:
// Native implementation
function isNaN(x) {
  // Coerce into number
  x = Number(x);
  // if x is NaN, NaN != NaN is true, otherwise it's false
  return x != x;
}

i wonder if there will ever be a time when instead of searching for hours for a built-in method to accomplish something, i'll think "hey, i could just write my own method" and then do it? it's not like it's a big deal to add new methods to a prototype

Hi
I have been using beta.freecodecamp.com. I have done the all the tasks but suddenly its not working . and it is changed to learn freecodecap.org .
when i login to the learn freecodecamp.org whatever the data is finished it is not restored.
Can you help me with that?
And How to get my previous data ?

@StevieY_gitlab Could you send the whole code?
Steve Yoo
@StevieY_gitlab
Jun 21 2018 08:57
Do you need the whole code? It's quite long
I dont understand what this means: Note that it is a good practice to end inline style declarations with a ;
Adam Jacks

Jun 21 2018 08:58
@StevieY_gitlab Nothing is wrong with that line

Adam Jacks
@AdamHJ123
Jun 21 2018 09:58
So you could have your <header> element
After your end it liek so </header>
You can open a <main> with id="main"
@nalinpuri Yes
nalinpuri

Jun 21 2018 10:08
I cant understand User story 1 @AdamHJ123
Adam Jacks
@AdamHJ123
Jun 21 2018 10:08
You must use a <main> element like so
<main id="main"> Your main content here</main>
nalinpuri
@nalinpuri
Jun 21 2018 10:09
In html
Adam Jacks
@AdamHJ123

@nalinpuri
Jun 21 2018 10:09

@AdamHJ123
Jun 21 2018 10:09
That is HTML

Jun 21 2018 10:16
That's not what a title is for
Title is used to change the name on the tab of your web browser
You want <header>
nalinpuri
@nalinpuri
Jun 21 2018 10:17
ok but is User Story it is telling me to write id as title
Adam Jacks
@AdamHJ123
Jun 21 2018 10:18
You can use <header id="title">
< h1 id="title>
Even <div id="squirrel">

https://codepen.io/lettiebear/pen/MXVpRV Would anybody be able to tell me why my headings throughout the page are not centered? I created it originally in sublime text and everything displays fine from the original html file, but for some reason once I put it into CodePen, my heading elements are not displaying correctly :(
Kyle Holm

Jun 21 2018 17:05

Aditya
@ezioda004
Jun 21 2018 17:15
@lettiebear The problem seems to be coping pasting directly (meta tags and such into HTML section), apparently codpen removes your <body> tags and inserts its own (you can inspect). You can put all the dependencies in the appropriate sections (CSS, JS) and start the HTML from <nav> directly and it seems to center it back.

@hensn5250 Do you have<meta name="viewport" content="width=device-width, initial-scale=1.0"> tag? This will make sure the website uses CSS pixels instead of device pixels, in short the page will follow the width of the device.
Also this article might help.

Create a second p element after the existing p element with the following kitty ipsum text: Purr jump eat the grass rip the couch scratched sunbathe, shed everywhere rip the couch sleep in the sink fluffy fur catnip scratched.
your second text doesn't look anything like the text in the instructions

Purr jump eat the grass rip the couch scratched sunbathe, shed everywhere rip the couch sleep in the sink fluffy fur catnip scratched.

i don't see any issues on github or questions on the forum
maybe i'm wrong, but it does seem odd

Hey guys! If I have an app with multiple html pages, in order to style them, should I use a single css/scss file or it's good practice to have a stylesheet for each html file?

@mehdiamlal You could use partials if you know how. If not you will prob learn later. I which case I would use one style sheet and use different selectors
