HackerNews discusses pros, cons, and impossibilities of JS obfuscation

 

It’s very hard to reliably obfuscate Java Script because the language is dynamic enough that you might refer to object fields or function names through dynamically-computed strings. Any attempt to obfuscate these runs up against the halting problem. So you have to rely on conservative approximations...
