The JavaScript method setInterval EXPLAINED in 5 minutes!

• The JavaScript setInterval() method executes a specified function multiple times at set time intervals specified in milliseconds (1000ms = 1second).
• The JS setInterval() method will keep calling the specified function until clearInterval() method is called or the window is closed.
• The JavaScript setInterval() method returns an ID which can be used by the clearInterval() method to stop the interval.
• If you only need to execute a function** one time**, use the setTimeout() method.

Usage of JavaScript setInterval

JavaScript interval to be set use setInterval() function. It could be defined simply as a method which allows you to invoke functions in set intervals.

The JS setInterval() function is similar to the setTimeout method. How are they different? Well, setTimeout() calls functions once. However, with the set interval method you can invoke them multiple times.

Let’s say you need to display a message to your website visitors every 3 seconds. By applying the JavaScript setInterval() function, you will be able to perform this task and incorporate a new feature on your website.

However, we would recommend not to overuse this function as it might disrupt the overall user experience. The following code example shows the way the message is set to be displayed every 3 seconds:

Example

setInterval(() => {
  alert("Hello"); 
}, 3000);
