How does each browser expose intermediary representation of JavaScript?

Question:

I've heard people use the terms dynamic compilation and interpretation interchangeably. This isn't a question about semantics.

Obviously by the time the code hits the processor it is in some binary form.

How can I look at intermediate represenation?

For example, it is pretty easy to look at your C code in assembly by using compiler options.

Is there a similar way to do this with JavaScript? I'm not sure what the intermediary representation would be called but here are some general references.

Research

Clarification:

This question has nothing to do with minification.

If you build V8 yourself by compiling the d8 shell, you can run d8 --print_code or d8 --print_opt_code. You probably want to output this data into a file.

See if these slides from Vyacheslav Egorov's mö.js JSConf talk get you any closer to what you need.
