Answer 3

I use Steve Yegge's js2-mode , and like it a lot. It's quite configurable, its indentation ideas match mine, and most impressively it has a full JavaScript parser in it, so it can alert me to syntax errors as I type (indispensable for little things like trailing commas in property lists that bork IE).

Answer 4

Espresso mode is supposed to be quite good as well.
