Summary:

Elixir in Action, Second Edition teaches you how to build production-quality distributed applications using the Elixir programming language. Author Saša Juric introduces this powerful language using examples that highlight the benefits of Elixir’s functional and concurrent programming. You’ll discover how the OTP framework can radically reduce tedious low-level coding tasks. You’ll also explore practical approaches to concurrency as you learn to distribute a production system over multiple machines.
