Learning YUI from scratch

I am new to YUI and I want to learn it from scratch. Can you suggest some books or tutorials? Where should I start? It seems YUI 开发者_开发问答3 is different from its predecessors. Please help me.

Please go through this page, http://developer.yahoo.com/yui/3/

The YUI 3 Cookbook is an excellent source of information for getting started with YUI 3. http://www.amazon.com/YUI-3-Cookbook-Cookbooks-OReilly/dp/1449304192

I would start with YUI 3 (most current is the YUI 3.2.0 preview release), but if you go the YUI 2.x route, YUI 2.8: Learning the Library was recently released.
