Learn Functional Programming with Elixir

Chapter 2 Working with Variables and Functions

Variables and functions are the fundamentals of any functional language, and Elixir is no different. It’s important to have a solid understanding of how they work so you can be comfortable working with the various types of functions. In this chapter, we’ll use Elixir to explore the basics and build a solid foundation for the upcoming advanced topics.

Our first topic will be values. In Elixir, valid values include strings, integers, floats, lists, maps, functions, and a few more. Yes, functions are values here, as you’ll see later in the chapter. But first, let’s take a look at how we can represent common values and their types.
