p5js.org. It is a beginner-friendly website for creating stuff in JavaScript straight into a browser. They also have resources and tutorials. After trying to learn coding for a long time, this is the place where it finally clicked for me.
codewars.com is great if you're into coding puzzles. It has them in just about every language imagineable. I'm amazed it's not more well-known cos it's a great site.
The problem with "what to buy to get started" is that that question is tantalizingly juicy to advertisers. Therefore, when a place is found it is usually captured by low quality high dollar cost advertisers (like reddit or amazon or essentially all the other sites that carry and recommend hobbiest products).
I think your best bet is to get to know a few people who actually are doing the hobby (not a advertising influencer) and see the cost points for real hobbiests.
I usually use ddg to search for sites, lurk there for a while to see what the questions and answers are and after a while either ask a question myself, when I like the site and haven't seen the questlon with appropiate answer in search results. That is, when I'm not member of a RL club and they have meetings/a site I can find the answer.
This website is helpful for finding anime to watch. It has a robust tag and recommendations system. If you don't know where to start I picked a favourite of mine.
