There is only one way to learn: have a problem then solve it. It has to be a real one, too.

So go and find (small) problem, work out how to solve it and implement it. Then if you really want to learn: promote and sell the damn thing.

Thanks for this practical advice - I guess what you're saying is it doesn't matter if it's JS or Ruby or whatever, just play around until you figure it out. Will give that a shot.
