Obfuscating your code is short-sighted. If you think you need to do this for the Web, you're missing the point.
If you've programmed something so wonderful that you deserve all the credit for it, first of all, congratulations! Secondly, put it on GitHub or a Version Control system, and share it with the world. You'll never advance in the programming world by obsessively hiding your code, you'll waste 20% of your time obfuscating, and for what? So you can get paid more? Good luck with that, man.
Computer Science majors used to obsessively compete to see who could make a script as concise as possible. JavaScript programmers in GreenSock are dependent on the Web, which is based on open source technologies. I hated the CS approach, as it presented programming as an individual exercise in problem-solving. If you've ever programmed in a business environment, you probably know that working on your own is very rare.
My point is that, in addition to all of the code used to make the Web being open-source, Web programmers enjoy and support a community of sharing that negates the old approach of individual competition. If you want to obfuscate your code, go learn C++ or something that uses a compiler. Go dust off a ****** old Flash project. But don't try to obfuscate your Web code. And please don't use an open Web forum, where programmers share coding techniques, to argue for code obfuscation. So you can make more money. This is a space for sharing code, not obfuscating.
