YOUR ELIXIR LEARNING PATH

A little more Elixir.
A little more confidence.

One idea at a time, with examples you can follow and checkpoints to see what’s clicking. New here? Begin with chapter one. Know a little already? Jump right in.

Before you start

Basic function and collection experience is helpful. Start with immutable values and pattern matching before processes and concurrent programs.

Review a foundation whenever you need it: Small functions · Lists, sets, and dictionaries
