In the world of JavaScript, asynchronous programming is a fundamental concept that allows us to handle non-blocking operations efficiently. While callbacks were the traditional approach, they often led to the infamous “callback hell,” making code difficult to read and maintain.

Enter Promises, a more structured and elegant solution that paved the way for the introduction of async/await, a syntax that makes asynchronous code look and behave more like synchronous code.

Promises are objects that represent the eventual completion (or failure) of an asynchronous operation and its resulting value.

They provide a standardized way to handle asynchronous operations, making it easier to manage complex control flows and error handling. Understanding Promises is crucial for mastering async/await, as async/await is built on top of Promises. Let’s dive into Promises and explore how they form the foundation of async/await in JavaScript.

Creating and Consuming Promises

A Promise can be in one of three states: pending, fulfilled, or rejected. When a Promise is created, it starts in the pending state and…
