Yahoo! UI Library

Today, Yahoo! released a set of Javascript-based UI libraries aimed at making it easier to build rich, cross-browser user interfaces. From their site: The Yahoo! User Interface Library is a set of utilities and controls, written in JavaScript, for building richly interactive web applications using techniques such as DOM scripting, HTML and AJAX.

I commend Yahoo! for their initiative, and to be honest, I am suprised that Google didn’t do this first. While several other libraries that accomplish the same thing have been available for a while now, this is the first one to come from one of the Internet heavy-weights.

Also of note is Yahoo’s Design Patterns site, which gives some insight into the thoughts behind some common UI elements on their site.
