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

In functional programming, functions are the primary tools for building a program. We cannot create a useful program without writing or using functions. They receive data, complete some operations, and return a value. They are usually short and expressive.

Multiple little functions are combined to create a larger program. The complexity of building a larger application is reduced when the functions have these properties:
