Yahoo! User Interface Next Generation JavaScript and CSS library
YUI 3 is Yahoo!’s next-generation JavaScript and CSS library. It powers the new Yahoo! homepage, Yahoo! Mail, and many other Yahoo! sites. The YUI 3 Library has been redesigned and rewritten from the ground up incorporating what we’ve learned in five years of dedicated library development. The library includes the core components, a full suite of utilities, the Widget Infrastructure, a growing collection of widgets, CSS resources, and tools. All YUI components are BSD-licensed and are available for forking and contribution on GitHub. In addition to the core components included in the YUI 3 Library, there is also a gallery of components created by developers in the YUI community that provide additional functionality leveraging YUI 3 that can be used in the development of robust web applications. Features would be
- lighter (less K-weight on the wire and on the page for most uses)
- faster (fewer http requests, less code to write and compile, more efficient code)
- more consistent (common naming, event signatures, and widget APIs throughout the library)
- more powerful (do more with less implementation code)
- more securable (safer and easier to expose to multiple developers working in the same environment)
