JavaScript is a powerful programming language known for its ability to handle asynchronous operations efficiently. One of the fundamental techniques used in async programming is setInterval().

This function allows you to execute a piece of code repeatedly at fixed time intervals. Understanding how it works can greatly improve your application's performance and user experience.

What is Asynchronous Programming?

Asynchronous programming means running multiple tasks concurrently rather than waiting for each task to complete before moving on to the next one. It enables developers to build highly responsive and interactive websites by allowing them to run long-running or resource-intensive tasks in the background while continuing to interact with users.

Understanding SetInterval()

The setInterval() method takes two arguments: a callback function and an interval duration in milliseconds. The callback function will be executed repeatedly every specified number of milliseconds until clearInterval() is called…
