Terse and you don’t learn anything. You should build levels and offer explanations to YOUR code.
algodaily.com has some really good explanations

#12I'm not convinced coding on a phone will ever be a thing. I've tried a few challenges on my phone while interviewing and it was just a clunky and slow experience

#13Not sure what the test cases are for the Fibonacci sequence (just happened to pick that one first), but it gives an error for my code, and I'm not able to figure out why. (please ignore my bad variable names) function(index) { var fib = [0,1]; for(var i=2; i
Your function will return 2 for index = 4, whereas it's expecting 3.
Then are the instructions not clear enough, or am I just missing something....
From the website: "For example, the sequence [0, 1, 1, 2, 3, 5, 8, 13, 21, 34] forms the first ten entries of the Fibonacci sequence." Entering 4 should return 2 in this case, which is correct? I don't get it.

I don't think coding an entire app ever will be. But mini training exercises? Maybe.

AWD editor has a built in sftp plus something like juicessh for command line server access makes it not too bad even on a small phone.

#16I think coding on a phone is doable if we "rethink" the keyboard part.
I've built a PoC (also a Web app, but requires a backend), video demo here:
The neat thing is that all the heavy-lifting of syntax highlighting, autocomplete, etc are done by Vim, so I don't need to port everything to the front-end.

Index 4 is the fifth element, 3. Index 0 is the first element (a zero).
Reread the examples.

#18I like the initiative, but the 'editor' on desktop is just an input field. Would have benefited from something like Ace Editor or CodeMirror.

#19The test cases for the Fibonacci sequence is terribly bad, you can cheat by returning fn = n=>[0, 1, 1, 2, 3, 5, 8, 13, 21, 34][n]
You need random test cases and larger test cases.
Codewars is definitely better than this.

#201) would benefit from some kind of keyboard help so that it’s not capitalizing every first character.
2) getting errors when trying to use single or double quotes which makes things difficult:
>SyntaxError: Invalid character '\u201c
Otherwise, nice work.
