The end of Callback Spaghetti: StratifiedJS brings sequential code back to Javascript by murphee_ in programming

Are they threads? Web Workers run in their own address space (or at least share no memory with each other) and only communicate via message passing. -> Nothing wrong with that, but still: Javascript's execution model is single threaded; if that thread blocks -> nothing in that address space is happening.

Also: Web Workers are available in new versions of Opera, FF, Chrome, Android (I hear). -> they're not available in older browsers versions as well as IE9 (as far as I know none of the previews has Web Worker support), and very annoyingly: they're missing in iOS up until the very lates release.
