Callback functions

Callback functions are a fundamental concept in programming, particularly in JavaScript. They are functions that are passed as arguments to other functions and are executed at a later time, allowing for flexible and dynamic code execution. This mechanism enables developers to create higher-order functions that can accept other functions, enhancing code reusability and modularity. Callbacks are essential in both synchronous and asynchronous programming, facilitating tasks such as event handling and managing asynchronous operations. Understanding callback functions is crucial for mastering JavaScript and improving overall coding practices.
