Understanding JavaScript Callbacks, Promises, and Async/Await JavaScript is a single-threaded programming language, which means it executes commands sequentially, one at a time. However, modern web applications often require performing time-consuming tasks without blocking the main thread, such as fetching data from a server. To manage such asynchronous operations, JavaScript provides several mechanisms: Callbacks, Promises, and Async/Await. In this article, we’ll explore each of these concepts, highlighting their advantages, pitfalls, and best practices. 1. Callbacks A callback is a function that is passed as an argument to another function and is executed after some operation has completed. This approach allows developers…
