Just a heads up, OP; I thought the title implied that js.js was somehow faster than javascript.
PS: Some "Python" in above sentences might actually be rpython. But as it is subset of python it probably doesn't matter.
This is far overreaching and as such very wrong. Also, "x language is faster than y language" is a meaningless comparison. Faster at what? In what cases? Pypy does some things faster than Cpython in some cases.

I don't know for sure that this is wrong, but it sure seems to be.
As for the PS; RPython is statically typed Python (perhaps some other extra restrictions apply). Not type-annotated or anything, just pure python written in a certain way. So it is a subset. As for what "Python" should have been "RPython", it was the first one. The pypy interpreter is written in RPython. But my statement was still correct because RPython is Python.
IIRC it was due to better cache locality.
