a compiled language, yes. But the function of a compiler, between a compiled language and an interpreted language, remains the same. It translates code from one representation to another.
Just because V8 has a compiler, doesn't make it a compiler. Do you see the difference?
V8 is a JIT compiler. It both compiles code and runs it. For your original complaint about not being able to compile JS up front, you're talking about Ahead-Of-Time (AOT) compilation. You don't seem very familiar with the relevant terminology.
In fact, I just looked it up and apparently V8 compiles JS directly to machine code rather than bytecode: https://en.wikipedia.org/wiki/Chrome_V8.
