js-box2d-lite

A JavaScript port of Erin Catto’s box2d-lite.
This is a near 1-to-1 port of the original C++ code, with little to no focus on JavaScript-specific performance optimizations. An optimized version may be explored in the future (for example, using scalar math instead of frequent object allocations).

Original C++ implementation: https://github.com/erincatto/box2d-lite
