What do you mean by "multiple cores to optimise a single threaded piece of code?" This makes it sound like code can automatically become multithreaded which is not true (threading is one of JS's great weak points).

v8 is an amazing piece of engineering but it's not at the point where it allows application developers to take much advantage of SIMD, hyperthreading, or multicore.

I think he means this is done behind the scenes without your knowledge (some compiler/runtime magic), not some interface you can take advantage of.
