JavaScript is a versatile language that can handle a multitude of tasks, from manipulating the DOM to handling server requests. One of its most powerful features is its ability to manage asynchronous operations. Traditionally, asynchronous code in JavaScript was managed using callbacks, but this approach often led to complex and difficult-to-maintain code, commonly known as "callback hell." To address these challenges, Promises were introduced in ECMAScript 6 (ES6), offering a cleaner and more manageable way to handle asynchronous operations. What is a Promise? A Promise in JavaScript is an object that represents the eventual completion (or failure) of an asynchronous operation and its resulting value. It allows you to write asynchronous code in a more synchronous-like fashion, making it easier to read and maintain. A Promise has three states: 1. **Pending:** The initial state, neither fulfilled nor rejected. 2. **Fulfilled:** The operation completed successfully. 3. **Reject...
