A popular discord community, a good mix of experienced people with a bunch of beginners: https://theprogrammershangout.com/

Nothing against that community at all but I hate discord. Maybe I am old but I don't see how it's good for communities.

If you’re old and hang out on HN you probably like IRC?

The benefit of discord is probably that it is extremely easy to join, and it seems like they have easy access to mod tools and bots and whatnot.
