Koans are a great way to practice test driven skills and learn by doing. elixir-koans is a nice repo to learn Elixir syntax by getting tests to pass. You can try doing 10 minutes a day or solve them all in one go if your that way inclined 💪.

You can leave this command running and fix the tests one by one. When you save the files it will re-run the tests and show you your progress.

An example

Just as an example I'll give you a solutions to show you... hitch hikers guide to the galaxy reference.
