JS programmers don't need to know how a C pointer works, but they're not doing themselves any favors by being ignorant of it. It's very basic basic background knowledge.

I meant to say they do not need to be great beyond basics like using wild cards, and simple Inclusion and exclusion syntax. That’s probably more than 50% of time all you need on that side of he world

Yeah, that's true. If you understand the quantifiers and matching groups, you basically understand regex. That's all I'm referring to. I'm not saying everyone has to be an expert on implementing them.
