Introduction

JavaScript is a single-threaded language thus by default, it is synchronous by nature, still, we can perform Asynchronous operations in JavaScript using promises, async/await which in turn allows developers to write efficient and scalable code. However, asynchronous programming can be a bit challenging to understand, especially for beginners. Today in this article we’ll be going deep dive into JavaScript’s async programming concepts.

What is Asynchronous Programming?

Asynchronous programming is a technique that allows your code to execute multiple tasks parallelly, without waiting or blocking any other task. This approach enables your program to respond quickly to user interactions, improving overall performance and user experience.

The Problem with Synchronous Code

Synchronous code, on the other hand, executes tasks sequentially, one at a time. This approach can lead to performance issues, as your program may appear unresponsive or slow while waiting for tasks to be completed.

Introducing Async/Await

Async/await is a syntax sugar on top of promises that makes asynchronous code look and feel synchronous. This syntax allows you to write async code…
