Promises

In this lesson, you'll learn about promises in JavaScript, which provide a more readable and manageable way to handle asynchronous operations compared to callback functions. Promises help you avoid "callback hell" and make it easier to handle both successful and failed asynchronous operations. ## Promises In the last lecture, we witnessed the challenges of callback hell. Promises come to the rescue by offering a cleaner and more structured way to handle asynchronous tasks. #### What are promises? They are objects that represent the eventual completion (or failure) of an asynchronous operation and its resulting value. Promises can either return the successfully fetched data or an error.
