Functional Programming in JavaScript - what are 'higher-order functions'?

The article 'What is a Higher-Order Function and Why Should Anyone Care?' by J.R. Sinclair introduces readers to the fascinating concept of higher-order functions. These functions, which are a key element of functional programming, are capable of taking other functions as arguments or returning them as results. This capability allows programmers to write more concise and flexible code. The article also discusses how higher-order functions can help organize code by enhancing its modularity and enabling the creation of more universal and reusable components. Additionally, the author provides practical examples of higher-order functions, illustrating their application in everyday programming. Understanding this concept is crucial for those wishing to expand their programming knowledge, as it is becoming increasingly prevalent in modern source code.
