In the fast-paced world of JavaScript development, efficiency is key. Asynchronous programming with promises has become the norm, but did you know there are advanced patterns you can leverage to supercharge your code?

In this guide, we’ll explore two powerful techniques — memoization and lazy loading — using promises. These patterns can help you optimize performance, reduce redundant computations, and enhance the overall user experience of your applications.

Understanding Advanced Promise Patterns

Before we dive into memoization and lazy loading, let’s quickly review the basics of promises in JavaScript. Promises are objects representing the eventual completion or failure of an asynchronous operation. They allow you to work with asynchronous code in a more elegant and manageable way, using .then() and .catch() to handle success and failure respectively.
