Details
Our current array representation can be slow when dealing with 32-bit integers and doubles. We want to introduce arrays backed by typed vectors instead of a vector of jsvals and use jsvals as fallback only. We also want to tighten the read/write path and remove hole counting and avoid updating both (fill and length) at every set. Detailed plan of work to follow.

Did Typed Arrays take care of this?

Typed arrays are user-specified, this was about vanilla arrays. The read/write path and hole/file/length situation is much better now with TI. Using typed vectors instead of jsvals is now covered by bug 689745.
