Is it possible to see the "optimized" version of Javascript running from the browser?

I recently started to study compilers and learned that, in an intermediate phase of the whole process, there may be a number of parsing passages aimed at improving the performance of the code (in this context in his intermediary representation).

It is no secret that Javascript interpreters (such as the V8) perform an absurd number of optimizations to make code faster, more efficient etc.

I wonder if it is possible to see the code (in any representation readable by a human being) with these modifications. It doesn’t necessarily have to be in Javascript, since, as far as I know, the code wouldn’t even be represented in the language anymore source original.

    I know that Javascript is not the language in which performance is the main goal. However, I still think it is valid to know which optimizations are made, even so I can be aware of these improvements.
