Exercises from Chapter 4: Handling Errors Without Exceptions

This repo is part of my blog series on Learning Elixir in which I work through exercises from Functional Programming in Scala using Elixir.

These exercises have a companion post that describes some of the more interesting exercises in detail: Error Handling in Elixir

If you'd like to work through the exercises yourself you can use my tests as a guide. To do this:

1. Clone the repo
2. Remove lib/handling_errors_without_exceptions.ex and replace it with an empty file.
3. Run mix test
4. Implement functions until the tests pass
