I’m confused between the two. Which is better, especially for jQuery and JS? Also, which do you think is more SEO-friendly? Note: I’m a noob.
None of them. It will not be indexed (only in obscure odd cases).
Minifying JS is about loading speed and obfuscating JS is for making it harder for other developers to read your code.
This is because most user-agents (e.g. browsers) can only make 2 simultaneous requests on the same domain.
