Welcome back to my 4th post in this series where I share key learnings from each chapter of Programming Elixir 1.6. If you haven’t read my previous posts yet, feel free to check those out first before continuing. In this post, I’ll be discussing anonymous functions in Elixir.

Chapter 5

1. Basic syntax of anonymous functions

Anonymous functions begin with the fn keyword and end with the end keyword. In between the fn and end keywords, you declare your parameter list followed by your function body. So far, this is very similar to other languages like JavaScript and Ruby.
