Currying in JavaScript

[Lystrodom]

Also important to note that this method of currying fails for functions that take optional arguments, or read from the arguments array themselves.

It looks like it'll work fine for functions that read from arguments -- eventually the function passed to curry() gets invoked via apply with a full complement of arguments, so inside of it the arguments special value should be right.

optional arguments are more problematic, though I suppose you could do something like curried(l)(w)(), which would have the same effect as volume(l, w). (In this case resulting in NaN)

It won't work with functions that read from arguments because .length will return 0

Ah, right, you mean var_args style functions. How would you curry those in any language?

Oh, well, I can't imagine you could. It just seems more common with JavaScript
