Elixir is a functional programming language that runs in the Erlang VM, a powerful environment to run distributed systems. This course uses Elixir because of its fun syntax, vibrant community, and production-ready tooling. Elixir syntax lets you focus on what’s important while learning functional programming.

Starting from scratch, you will learn the fundamentals of Elixir including expressions, modules, conditional statements, and recursion. Towards the end of the course, you will focus on more advanced material like higher-order functions, how to handle impure functions, and lastly how to design an application using Elixir and functional programming principles.

By the end, you will be able to write basic Elixir programs that follow the functional programming paradigm.

Learn Functional Programming with Elixir

That was a challenging chapter! We’ve used everything we covered in the previous chapters to build a larger application, and we faced some new concepts. Let’s review them:

- We covered how to start a project with Mix and its basic commands.
- We saw how to structure the project in folders and namespaces.
- We created customized structs to describe our domain.
- We used Elixir protocols to achieve polymorphism.
- We used Elixir behaviors to create a contract between modules.

Get an overview of what we have covered so far in this chapter.
