cannon-es.js is a smaller 3D physics library than Ammo that is written in JS. This can be a great alternative if download size or space is an issue (e.g playable ads, messenger games etc)
A basic integration of the library can be found here: https://playcanvas.com/project/793652/overview/cannonesjs-physics-integration
