Faster, ligher JS library: üjs

This type of jokes that just scream "April 1st! April 1st!" are not my favourite...

Not fast or light enough for me, i only use vapor.js<p><a href="http://vaporjs.com/" rel="nofollow">http://vaporjs.com/</a><p>It's not even an april fools joke....

I'm considering using it for my bootstrapped startup. Anybody know how it compares to ExtJS?
