In this book, you will find descriptions of programs that you can write in Elixir. The programs will usually be short, and each one has been designed to provide practice material for a particular Elixir programming concept. These programs have not been designed to be of considerable difficulty, though they may ask you to stretch a bit beyond the immediate material and examples that you find in the book Introducing Elixir.

Elixir is a functional, meta-programming aware language built on top of the Erlang VM. It is a dynamic language that focuses on tooling to leverage Erlang's abilities to build concurrent, distributed and fault-tolerant applications with hot code upgrades.
