This is a bit unorthodox, but I personally got a lot out of taking the LISP code in Structure and Interpretation of Computer Programs, and mentally translating the examples and solving the exercises in Javascript. There's apparently versions of the text around with the exercises pre-translated, though translating it myself was valuable to me.

Obviously, this will more teach you how to write good code that happens to be in Javascript, rather than taking an already-solid programmer and showing them the nitpicky details, idiosyncrasies, and browser APIs of Javascript.
