I want to make a website using TDD. But I want to read and practice with a couple of small projects first. I'll read it, and then try it myself and check my implementation with the repository.
This is what I've found:
**npm modules** usually have tests:
**katas, exercises, challenges**:
[exercism](https://github.com/exercism?q=&type=all&language=&sort=stargazers) has a repository for each language, with exercises and tests.
