Programming Elixir

Part 3More-Advanced Elixir

Among the joys of Elixir is that it laughs at the concept of “what you see is what you get.” Instead, you can extend it in many different ways. This allows you to add layers of abstraction to your code, which makes your code easier to work with.

This part covers macros (which let you extend the language’s syntax), protocols (which let you add behaviors to existing modules), and use (which lets you add capabilities to a module). We finish with a grab-bag chapter of miscellaneous Elixir tricks and tips.
