Stuff like (fab) and CoffeeScript* show how easy it is to build on top of the V8 and node.js platform. And these toy languages/frameworks also have great perfomance given the non-blocking nature of node.js and the optimizations of V8. Amazing and happy to see more of these projects :)<p>* <a href="http://jashkenas.github.com/coffee-script/" rel="nofollow">http://jashkenas.github.com/coffee-script/</a>
