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 does for for PHP?

  • Ahem... the ECMAScript specification? One would assume that the specification of a programming language defines the built-in object of that language... – Šime Vidas Commented Nov 19, 2011 at 17:44

I find Mozilla's MDN to be pretty prehensive.

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)

Have you seen JavaScript Reference on Mozilla Developer Network?

As mentioned in a ment, the ECMA specification (pdf), on which Javascript is based, is the official place to find that information.

window, incidentally, is technically not a built-in object, at least not by that name. It's known as the host object, which happens to be called window in web browsers, but is actually implementation-dependent. The host object is where global variables are stored.

That's one of the neat things you find out when you * cough * read the spec (pdf).

I was googling for the same thing (equivalent to php for php) and found the following
