Best place to learn JavaScript?

I need to learn JavaScript for some client-side parts I need to do (no, not alert("welcome to my web sight lol h4x"), but real stuff).

I've fucking Googled it, but JS sites seem to teach alert("welcome to my web sight lol h4x").

Do you know of any good, serious language references not intended for noobs? The kind of thing you'd get for any other languages. I need something including a detailed language builtins explanation, DOM level 1, regular expressions, and all the new methods.

Thanks in advance.

Stay away from these links. Web 2.0 cargo-cult circlejerking is not much better than the DHTML cursor trail/expanding menu fad that preceded it.

>>3 is good.
This is also good but it'll probably take quite a while to read!
