I know programmers sometimes write directly in assembly for certain performance enhancements and certain hardware access. Is there a foreseeable reason someone would program directly in WebAssembly though? I realize that's not the reason this technology exists, just curious.
When asm.js came out I ported http://wry.me/hacking/Turing-Drawings to use it. It would've made as much performance sense to do the same for WebAssembly. This is not quite the same as hand-coding WebAssembly -- it's making a custom code generator for a little language.
As far as I understands, this should be doable.
But it would probably be much easier to use another (static) language for the parts you want to optimize, compile to wasm and then access them in your js code.
