A good reference for Javascript built-in objects?

Question

Where can I find a good list and description of Javascript built-in objects?

I know there are things like Date, Array, String, window, Number, RegExp etc, but I can't find what methods they have anywhere. Is there a single authoritative place containing this information, like php.net does for for PHP?

Answer 1

I find Mozilla's MDN to be pretty comprehensive.

As for seeing what features are supported cross browser or not, quirksmode is great. (Although I think there are other sources that are better for the newfangled html5 stuff)
