What are Callbacks?
A callback is a function passed as an argument to another function, which gets invoked after the main function completes its execution. You pass the callback function to the main function as an argument, and once the main function finishes its task, it calls the callback function to deliver a result.
Callbacks enable you to handle the outcomes of asynchronous operations in a non-blocking way. This means your program can keep running while the operation is ongoing.
JavaScript Callbacks
JavaScript is built to handle asynchronous programming, allowing it to manage multiple tasks at once. Callbacks are important in JavaScript as they enable you to execute code after an asynchronous task finishes. This article explores what callbacks are, why they’re essential, and demonstrates how to use them with practical examples and code snippets.
