#2Terse and you don’t learn anything. You should build levels and offer explanations to YOUR code.

#3Not 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; iRe: PracticeJS – Coding exercises in a mobile friendly web app

Your function will return 2 for index = 4, whereas it's expecting 3.

#5Neat! Are there any programming keyboards for iOS out there that help with common operators /characters?
Can you add syntax highlighting to this?

#6Seems very procedural-oriented. Would be really cool to see a procedural and functional orient solution.

#7This seems very similar to codingbat.com. My CS teacher in high school made me do codingbat and it was very helpful; I could see this site doing the same for JS learners. Codingbat is not as mobiles optimized but is still usable on my phone. As another commenter mentioned, some important differences are:
Number of problems, sorted into levels of difficulty / focus areas (this has only one problem that I would consider 'hard')
Help (not just solution) is available to those who want it
Helpful error messages
Syntax highlighting
That said, I really like the interface here. It works well on my phone and looks nice on a desktop, and is straightforward and simple. The only issue is that keyboard auto capitalization/autocorrect gets annoying to deal with on a phone. Hacker's Keyboard (free software Android keyboard) could help with that; it would be nice to have a link to something like that for Android+iOS on the website.

Auto capitalization can also be fixed with a cheeky little `autocaptialize="off"` attribute.

I remember my first Fibonacci sequence

Messagease is really good for coding and typing at a shell prompt, etc.
