Most often I just start using the language without reading/watching tutorials.

And I often contribute to open source projects which I use, that use a language I've never used, and it worked quite well so far.

a) you can take a look what tooling they use

b) by looking at the existing code and trying to find the bug I often find interesting things that may be helpful for my contribution

c) most open source maintainers give reviews and may aid you with some parts of your code, and are often quite helpful when you are puzzled by their build steps or CI pipeline

Otherwise you could just go on GitHub and filter the top stared repositories that use the language and take a gander at their tooling and their code

And some languages like rust have good documentation for the tooling, common libraries used, and tutorials that are more advanced than crrating a hello world
