Re: the C++ thing.
Yup you can! That's actually how Expo's `GLView` (which exposes OpenGL ES as a WebGL'y API in React Native's JS context) works. The binding is done in common C++ code for both iOS and Android. Calling to that from Obj-C is straightforward, for Java you use JNI. This is binding is done manually and built once (not auto-exposed), then you can use the GL stuff in JS!
