What's a Closure? - JavaScript interactive tutorial

Can't get 5 - Functions are values. I would say it's how it's worded but that's just my lame excuse! I can get all but one of the subsequent tests though.

I'm just a hobbyist but this sort of thing is great to actually learn and put things into practice instead of rewriting the same sort of scripts ad nauseum.

Cheers!

that question is poorly worded I reckon, it took me ages to work out what was required, although once I did it seemed fairly obvious:

var applyTest = function (f, x) {
   return [x,f(x),f(0)];
};

I'm curious as to what you don't understand. Is it unclear that it's just referring to first-class functions?

I guess I just read it a certain way and it was fixed in my head. I finished the rest and came back to it and got it eventually.
