JavaScript, being a versatile and powerful language, relies heavily on functions to achieve various tasks. One essential concept to grasp is callback functions.
In this article, we will delve into what callback functions are, how they work, and provide practical examples to help you understand their importance in JavaScript programming.
What are Callback Functions?
In JavaScript, functions are treated as first-class citizens, meaning they can be passed around as arguments to other functions. Callback functions are functions that are passed as arguments to another function and are executed after a specific task has been completed or when a certain condition is met.
Why are Callback Functions Important?
Callback functions play a crucial role in asynchronous programming in JavaScript. They allow us to write more efficient and flexible code by handling tasks that depend on the completion of other operations without blocking the execution of the program.
