On Security Now this week, they mentioned Asm.js. This project by the Mozilla guys creates a subset of javascript that's pre-compilable, thus creating a huge performance boost for scripts. Even better, the fact that it's still valid javascript means that it runs in engines that don't support Asm.js. HUGOMORE42 This is a great idea, and could open up some scripting possibilities that were unfeasible even in Chrome's engine. I hope other browsers jump on this bandwagon!
