YUI 3 Sneak Peek

The YUI team released YUI 3.X for a sneak peek preview. The goals make me happy… especially goal 2.

1. lighter (less K-weight on the wire and on the page for most uses)
2. faster (fewer http requests, less code to write and compile, more efficient code)
3. more consistent (common naming, event signatures, and widget APIs throughout the library)
4. more powerful (do more with less implementation code)
5. more securable (safer and easier to expose to multiple developers working in the same environment; easier to run under systems like Caja or ADsafe)
