JavascriptOO maintains a directory of JavaScript libraries with examples, CDN links, statistics, and videos. Javascript landscape is changing by the day and sites like JavascriptOO makes keeping pace with it a little easier. Not all frameworks will last the long run ,natural selection will get the better of them, but having early access to the next big thing in javascript always helps. Some of the frameworks will sure make you chuckle and say “can javascript do that?”.
