Introduction to Higher-Order Functions
Explore the concept of higher-order functions in Elixir and how they simplify complex tasks by accepting functions as inputs or returning functions. Understand the use of higher-order functions for managing files and processes with safer, concise interfaces, and practice building reusable and efficient code using these principles.

Higher-order functions have functions in their arguments and/or can return functions. They are useful for hiding the complexity of tedious and laborious routines. Having functions in input and output enables developers to create simple interfaces to help other parts of the code focus on what matters. For example, let’s see File.open/3 in an IEx session: ...
