JavaScript development has evolved significantly over the years, introducing new features and techniques to enhance code readability and maintainability. One such advancement is the adoption of Async/Await, a syntax that simplifies asynchronous programming.

In this article, we’ll explore how to modernize your JavaScript code by converting callback-based functions to Async/Await, improving clarity and reducing complexity.

Understanding Callback-based Functions

Before we dive into conversion, let’s revisit callback-based functions in JavaScript. In traditional JavaScript, asynchronous operations were commonly handled using callbacks. Callback functions are passed as arguments to asynchronous functions and executed once the operation is complete. While effective, callback-based code can become difficult to manage, especially when dealing with multiple nested callbacks, leading to the infamous “callback hell.”

Enter Async/Await

Async/Await is a more modern approach to asynchronous programming in JavaScript, introduced in ES8…
