We used to have asm.js for that. For various reasons wasm is a replacement for it. JS doesn't even have proper integer types, it is not a good target language.

asmjs had an i32 type by (ab)using JS semantics and a common jit optimisation: bitwise ops are defined for 32 bits two’s complement integer. So x|0 necessarily results in an i32.
