Learn Functional Programming with Elixir

Wrapping Up

In this chapter, we started with the basics of functional programming, from simple expressions to building named functions with modules. Let’s review what we’ve done:

• We created simple expressions with Elixir values, literals, and operators.

• We created anonymous functions and used them as a new value type.

• We tested the variables’ immutability and scope.

• We created named functions and learned how to import functions to our modules.

• We used named functions as values.

In the next chapter, we’ll explore one of the most interesting features of functional programming: pattern matching. Learning how to use it will take your programming skills to a whole new level.
