If you do absolutely zero instruction optimization or re-ordering, JavaScript takes 0 seconds to compile, and you can use almost-complete feature set of ES6. /s

Come on man, that's beyond the point. Just because JavaScript needs to be compiled, doesn't mean it has a worse experience than compiling C++.

Instruction optimization is procedure of measuring expected CPU latency given the expected current state to identify which instruction set transition is optimal for the CPU. It would not be applicable to JavaScript unless I missed something.

Instruction ordering is largely bound to instruction pipelining and the estimation of CPU instruction transitioning to reduce latency. Given that V8 uses some degree of virtual indirection... I don't think that's possible in JavaScript.
