Elixir is an excellent language if you want to learn about functional programming, and with this hands-on introduction, you'll discover just how powerful and fun Elixir can be. This language combines the robust functional programming of Erlang with a syntax similar to Ruby, and includes powerful features for metaprogramming.This book shows you how to write simple Elixir programs by teaching one skill at a time. Once you pick up pattern matching, process-oriented programming, and other concepts, you'll understand why Elixir makes it easier to build concurrent and resilient programs that scale up and down with ease.Get comfortable with IEx, Elixir's command line interfaceDiscover atoms, pattern matching, and guards: the foundations of your program structureDelve into the heart of Elixir with recursion, strings, lists, and higher-order functionsCreate processes, send messages among them, and apply pattern matching to incoming messagesStore and manipulate structured data with Erlang Term Storage and the Mnesia databaseBuild resilient applications with Erlang's Open Telecom PlatformDefine macros with Elixir's metaprogramming tools
