Higher-Order Functions

Higher-order functions are functions that can take other functions as arguments or return them as output. Think of them as tools that manipulate or operate on functions, not just data. They enable more flexible and reusable code by allowing you to compose, modify, or generalize behaviors. For example, a higher-order function might apply a specific operation, like doubling a number, to each item in a list, or combine multiple functions into one. This concept promotes cleaner, more modular programming, often used in functional programming paradigms to increase code expressiveness and efficiency.
