Why is this upvoted so much? In what way is it better than any of the existing JS physics engines?

It should be possible (and relatively easy) to wrap it into a module that's callable from Javascript, similar to what Alon Zakai has done with the Bullet physics engine (https://github.com/kripken/ammo.js/).
