Learning Elixir

By: Kenny Ballou, Kenneth Ballou

Overview of this book

Elixir, based on Erlang’s virtual machine and ecosystem, makes it easier to achieve scalability, concurrency, fault tolerance, and high availability goals that are pursued by developers using any programming language or programming paradigm. Elixir is a modern programming language that utilizes the benefits offered by Erlang VM without really incorporating the complex syntaxes of Erlang. Learning to program using Elixir will teach many things that are very beneficial to programming as a craft, even if at the end of the day, the programmer isn't using Elixir. This book will teach you concepts and principles important to any complex, scalable, and resilient application. Mostly, applications are historically difficult to reason about, but using the concepts in this book, they will become easy and enjoyable. It will teach you the functional programing ropes, to enable them to create better and more scalable applications, and you will explore how Elixir can help you achieve new programming heights. You will also glean a firm understanding of basics of OTP and the available generic, provided functionality for creating resilient complex systems. Furthermore, you will learn the basics of metaprogramming: modifying and extending Elixir to suite your needs.

Summary


We covered a lot in this chapter, so let's take a quick moment to recap what we went over.

Everything in Elixir is a statement and this has a cool result on composability in the functional world. So, it's easier to compose expressions than statements.

We discussed the basic types of Elixir: numbers (integers, floats), atoms, booleans, Strings, lists, tuples, binaries, functions, and PIDs.

Furthermore, we spent some time covering immutability again and started our exploration of pattern matching.

Finally, we finished up with some discussion on structure, file formats, and scripts.
