Getting started with game development using js/html5

Question

Anyone have experience with game development using javascript and the html5 canvas element?

So far I have found two libraries, are either of these worth using?

http://tommysmind.com/ (XNA Port)

http://gamequery.onaluf.org/ (jquery plugin)

Does anyone have any other resources?

Answer 1

Have a look at Processing.js. Maybe you can use it for 2D drawing and user interaction.
