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.

A simple script that counts to 10, a homepage that shows recent news, a program that parses each line of a CSV file, what do these programs have in common? They all need to do repetitive tasks to determine the final result. Recursive functions are the core of repetition in functional programming.

In imperative languages, iterative features like `for` and `while` loops are responsible for repetition behavior. Both `for` and `while` loops rely on the mutable state. In functional programming, we have an immutable state, so we need a different approach. Here we use recursive functions.
