- Initialize environment.
- Generate bytecodes.
- Interpret and execute bytecodes.
- Compile and execute machine codes.
- Machine codes requires a great amount of memory.
- Machine codes are not always faster than bytecodes.

Does node js use V8 engine?
Why is V8 so fast?
What language is V8 written in?
Chrome V8/Programming languages
Is V8 faster than SpiderMonkey?
V8 is the fastest, because it compiles all JS to machine code. SpiderMonkey (what FF uses) is fast too, but compiles to an intermediate byte-code, not machine code.
Is V8 faster than Python?
V8 is absolutely faster than Python/Ruby.
