JS library to work with canvas

Question

Do you know a good js library to work with canvas? I've already tried with Processing.js but i want to know if there are some good alternatives to it.

Answer 1

Burst Engine might be worth a look:

The Burst Engine is an OpenSource vector animation engine for the HTML5 Canvas Element. Burst provides similar web functionality to Flash and contains a layer based animation system like After Effects. Burst uses a very light-weight JavaScript frame, meaning your animations will download un-noticeably quick and can be controlled using very simple JavaScript methods.

I think they're in the middle of a major rewrite though.
