Function Fundamentals

What Makes a Function Powerful?

Functions are the building blocks of clean, maintainable code. This module covers advanced patterns like closures, function composition, and higher-order functions.

// Basic function
function add(a, b) {
  return a + b;
}

// Arrow function with implicit return
const multiply = (a, b) => a * b;
