How to help the community
A lot of developers are helping the community by making their source code public or publishing packages to npm or something like that. Are there other ways to help? Like helping to find a bug, discussing about how to setup an application for a certain use case or anything like that? Answering questions on Stack overflow is an example but is that the best way?
Something a lot of open source projects lack are designers and UX experts. Translation is also something a lot of people can help with. Documentation writing too.
For the programming community at large, sharing knowledge is a great thing to do. There are many channels available, blogs, wikis, even videos on YouTube.
Documentation is a big thing that's unfortunately often overlooked. It's not as sexy as adding new features or fixing elusive bugs, but it can really make or break a project for others to use.
And not even documentation, even just adding examples without explaining anything can be so incredibly helpful.
There's a whole bundle of tools that will never be used because its too difficult to figure out how to use them.
Yes, folks, whenever you see a problem or get confused by something submit a fix for it! I've submitted a PR for a Vim plugin that mentioned some weird Vin task that I added the command to do the thing mentioned. My reasoning was that not everyone knows what that meant. They accepted. I hope it has helped more novice Vim users (like myself) once it was accepted.

Generally the best way to help out is to do a thing that's needed and that you can figure out how to do. Your list includes a bunch of good options, and I've been thanked for doing all those things at one point or another. Some common growth paths include:
Another path might be:
There are other paths as well, the main thing is to use a thing so you learn about it and then use that knowledge to make it a little easier for the next person. Good luck!
Which community? This is an extremely abstract and large scale question as asked lol.
I think a good way to help the open source community is to fix bugs you find in software and documentation you use that you're capable of fixing. Open source work is extremely easy to get burnt out on. A pull request with a fix for a well documented problem is infinitely better than just a bug report of a well documented problem (which itself is infinitely better than a badly documented bug report).
The "best way" depends on the project and its need, or immediate most pressing needs. You may refer to their contrib docs or ask.
But generally, any quantity and quality contribution helps. Community support and issue reproducibility and testing being low-barrier entry ones. Next lowest barriers being translation and documentation.
