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.

Upon hearing the term first-class citizens, it may seem like some functions are flying first class to Europe.  However, when we say that functions are first-class citizens in programming, we mean that they are like any other value. It’s an important feature that came from lambda calculus.

In Elixir, functions are values of type `function`. Let’s build a function that expects a function:
