Considering Starting Linux - eviltoast

I have been using Windows my entire life, but since I got my Steam Deck I’ve been considering trying to get into Linux.

I obviously don’t have much of an idea where to begin, other than that I’m currently also trying to learn Javascript. I’d like a basic workstation I can code on and mess with, that doesn’t run more than a couple hundred. Could use some recommendations for hardware plus where to begin.
