- Look at "skeleton" or "boilerplate" projects on GitHub. Don't copy the first one you find, make sure you review a handful and study how people are using the language and eventually make your own. Bonus if the project is from a contributor of the language.

- Some languages and frameworks have a "best practices" guide.

- RTFM!

- Iterate. Your first attempt will always feel hacky. Revisit it after more studying and practice.
