Is there a website that tells you real world uses of specific methods or things you're learning?

I’m learning about the match() function, which Im sure is very useful, but I can’t think of a reason that I would ever use this, is there a site that tells you a real world use of a lot of these concepts, functions etc?
Thank you for the help and incredibly sorry if there’s an obvious site I’ve been missing

I personally don’t think you’re going to find a site like that, since most people like to prioritize the versatility of coding.

That being said, I tend to use MDN Web Docs or W3 Schools to get a better idea of how a concept works, and sometimes there are specific examples included in the descriptions.

In general though, brainstorming about practical uses not only helps you remember the concept, but can help you better understand how it works, as well.
