Higher Order Functions

Higher-order functions are a fundamental concept in programming that refers to functions that can accept other functions as arguments or return them as results. This capability allows for greater flexibility and abstraction in code, enabling developers to create more modular and reusable components. In languages like JavaScript, higher-order functions are prevalent and are often used in functional programming paradigms. They facilitate operations such as mapping, filtering, and reducing collections of data. By treating functions as first-class citizens, higher-order functions empower programmers to write concise and expressive code, enhancing both readability and maintainability.
