asm.js solves this in the specific case where somebody has compiled their C/C++ code to target asm.js. It doesn't solve it for arbitrary JS code.

asm.js is more like a weird frontend to wasm than a dialect of JS.

No, if you just use the standard JavaScript cast to integer incantation, |0, v8 will optimize it. asm.js is valid JavaScript.

Sure, but that was essentially my point. If we're trying to compare HotSpot and V8 for similar input code, Java and asm.js seem closer than Java and full-blown JavaScript with its dynamic typing.
