V8 is a JIT compiler that uses the Ignition [1] interpreter and only compiles sections of code down to machine instructions once they've been marked as hot via TurboFan [2]. V8 can also go back and forth from machine instructions back to bytecode if it identifies that certain optimization assumptions no longer hold.
