ECMAScript 5 is on its way. Rising from the ashes of ECMAScript 4, which got scaled way back and became ECMAScript 3.1, which was then re-named ECMAScript 5 (more details)- comes a new layer of functionality built on top of our lovable ECMAScript 3.

One of my favorite sources of active mining is that of Peter-Paul Koch digging in to mobile browsers and how they behave.
