JS Physics library

HI,

I am ready for the LD42, but I have a problem in which I hope someone can guide me. I work with JavaScript and use Box2D for physics. But in the last two LDs when I tried to do complex things, the Box2D did not work as planned, the documentation is poor and it is not accurate according to the source code. My biggest problems are with the sensors and the collision filter (maskBits, categoryBits, ...).

Is there any Physics library other than Box2D that I can use in my JavaScript base code? I do not want to use a complete framework, because my base code is adapted to my workflow. thanks in advance.
