Elixir is in a fairly unique position as a programming language, in that it combines contemporary language features and excellent developer ergonomics with the established and battle-tested Erlang ecosystem.

Our journey starts with basic types and procedural logic. Even if you're experienced in a wide range of programming languages, there's going to be a lot of stuff -- even at this basic level -- that may change the way you look at writing code forever.

Elixir's module system allows us to define layers of related functions. In this part of the course, we'll explore the concepts of modules, and the ability to reference code in one module from another.

Earlier we outlined and worked with several different types of data structures. Let's take a closer look at some of these methods.
