JavaScript documetation

I need some online documentation on JS, does anyone have an URL regarding this?

http://www.irt.org is where I always look :)

W3C: They set the HTML and DOM standards. As a result, they have a page that outlines the ECMAScript (JavaScript) mappings to the DOM standard.

Mozilla's Webdeveloper Documentation: This has several valuable links. Some of them are old and before the standards were set, as a result they should be ignored. Others give a good break down of the ECMAScipt standard and how it ties to the DOM standard.

I like the XML DOM reference on this site:
http://zvon.org/index.php?nav_id=references&mime=html
I don't think they have much on the javascript language, though.

the w3 that ciberthug posted is one of the best.
