title: Get JavaScript bytecode
body: <p>I have read that Javascript source code first compiles to the intermediate representation(bytecode). Then bytecode compiles to the native code using jit.
  So I compile webkit on my linux machine, and want to get bytecode of source file.
  But I can't figure how to do that?</p>
  
  <p>How can I see/access the intermediate byte code that a javascript interpreter produces?</p>
