What do you mean by that? Java bytecode is leaps and bounds more instrospectable, and by that, I mean that programs can actually garner useful information from it, otherwise tools like Eclipse's code completion woudn't work. The source won't be preserved, but the class, field and method names will. That's much better than what you get from minified JS. I also mean that, despite its unconvenience, Java's reflection API is still quite powerful.

I don't get the fixation with the fact that the filename ends in a .js extension; just because a bunch of code is in a familiar interpreted language doesn't make it readable or maintainable in any other manner.
