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.

**Higher-order functions** have functions in their arguments and/or can return functions. They are useful for hiding the complexity of tedious and laborious routines. Having functions in input and output enables developers to create simple interfaces to help other parts of the code focus on what matters. For example, let’s see `File.open/3` in an IEx session:

```Elixir
iex> File.open("file.txt", [:write], &(IO.write(&1, "Hello, World!")))
```
