why get_ and set_ when js has getter/setter definitions? #13

Pomax commented 11 years ago

JS supports automatic code execution on get/set by defining an object property explicitly (using Object.defineProperty). Why is the port using the non-box2d get and set API rather than taking advantage of JS getter/setter functionality to preserve the "universal" Box2d API?

JS getters and setters tend to be slower than regular function calls, or used to be when the bindings generator was written.
