Where possible, we should move JavaScript to native/wasm code #15151

This is meta-issue for ongoing work for move as much code as possible out of JavaScript and into C/C++.

In particular it would be good to focus of code that does HEAP access from JavaScript. Doing this instead from native code has several advantages:

The syntax for heap access in JS much harder to read and write
JS heap access is currently slow when using ALLOW_MEMORY_GROWTH and USE_PTHREADS
Supporting wasm32 and wasm64 with the same JS code adds complexity (#12869)
