Minified and obfuscated Javascript is not much easier to check than binary files and more difficult than e.g Java class files, at least without ProGuard.
Oh there is a built in version in the Chrome debugger.
And it can sure handle js uglify, etc there are tools and systems that allow you to remove more than that and then it becomes really difficult to get a handle on WTF is going on.
Sure, but this one is much more advanced than the the one in the Chrome Inspector, which only formats. This one renames variables and functions, adds comments, and even annotates types.
