Choosing where to post
If you have a question, start in r/learnjavascript: it is set up for exactly that, and with about 3.1 new posts a day there are plenty of people around to answer. Asking the same thing in r/webdev often gets it removed or lost among the 87 daily posts. Competition for attention differs a lot: r/javascript has 2.5M members but only about 9.3 new posts a day — roughly one new post for every 264K members — while r/webdev gets about 87 a day, one for every 38.1K. A strong, well-made post therefore has more room to be seen in r/javascript; r/webdev is better when you want quick replies.
A simple rule of thumb: ask questions in the specialised communities and share your best finds in the big ones, where they can reach the most people. Always read the rules in the sidebar first — each community is run by its own volunteer moderators. Our guide to searching Reddit explains how to dig through any of these communities, and the subreddit info tool gives you the stats of one we don't list.
