Ammo.js

The autogenerated bindings require verbose getter/setter functions for member variables and careful use of 'new', leading to error-prone code, as noted in the troubleshooting section.

Building from source demands Emscripten and cmake setup, with options like closure compilation, which adds overhead compared to drop-in libraries.

The full Bullet port results in substantial file sizes, and reducing them requires manual editing of ammo.idl or build flags, as admitted in the 'Reducing Build Size' section.

The README focuses on C++ porting and build instructions, with limited guidance for JavaScript users, relying heavily on example code that may not cover all use cases.
