I can second this recommendation. JS is an odd bugbeast in that it took some design shortcuts early in it's life that aren't really visible without this kind of "here are your primitives" review. It also works like any other language primer in that it doesn't go into needlessly specific domain bound examples. That kind of stuff should be in a stdlib-eqsue doc.

A good read for even for some one like me, who slings JS almost daily.
