1. The Good Old setInterval() Method

The setInterval() function is a classic and straightforward approach to executing a piece of code repeatedly at a specified time interval. Here's how it works:

let intervalId = setInterval(function, delay, param1, param2, ...);

• function: The callback function to be executed repeatedly.
• delay: The time interval in milliseconds between each execution of the callback function.
• param1, param2, ...: Optional parameters to be passed to the callback function.
