I’ve just tinkered with wasm and rust, but it was surprisingly pretty straightforward. It seems there a huge amount of effort being placed in the ecosystem. Great project so far! I’ll have to check out the bom tools.
Emscripten compiles to asm.js, which is just a subset of JS. CanIUse will tell you some browsers don't support it, but it really means they don't support accelerating it. Your code very well may still run in those browsers (but I'm not sure about the determinant of those cases).
