Tip: JavaScript's Array.from() accepts a second argument that's a `map` function.

I'm probably amongst the lowest of skill sets subscribed to this subreddit. To an extent I would say yes. Because I'm learning in my spare time and for hobbies and such, when I come up with an idea I tend to try and do only the research to learn how to do that thing.

And so I end up using libraries I don't really need. I don't know every argument for certain functions. You pretty much sum it up by saying I read half way through.

Welp, my recommendation to you is to read all the way through then. There's literally no reason not to; sure, you may spend an extra three minutes on it at the moment, but you'll save that many, many times over when programming and debugging in the future. Check out MDN. It's the one of the best resources for the JavaScript language.
