Learning Elixir: Function Composition

Function composition in Elixir involves building complex functionality by combining small, single-purpose functions rather than writing large monolithic ones, leveraging techniques like the pipe operator (|>), anonymous functions, and higher-order functions to create reusable and testable code. The article demonstrates composition methods including manual nesting, piping, and creating new composed functions using function references, showing how to chain operations like doubling and incrementing numbers into a single composed function. This approach improves code readability, testability, and maintainability by allowing functions to be easily reused, modified, and rearranged.
