I think you're confusing JS minification with obfuscation. Minified code looks obfuscated, sure, but it's not done to deter "hacking", just to make the code smaller.
I'm not talking about the challenge, but those supposed commercial JS libraries with DRM that you're advising "should take notice".
There are no mainstream examples of such libraries. You're likely confusing minified libraries for having an intent to obfuscate, or talking out your ass.
