You can use the "setInterval()" function in JavaScript to make your code run repeatedly on a timer. This can be super useful for clocks, counters, updating your page with live data or even creating games.

To use this function, you supply it with a "handler function" which will contain your code that you wish to execute repeatedly. You also provide the function with a delay in milliseconds - which actually sets the interval.

In this video I take you through a straightforward example of the "setInterval()" function where we display a number on the page and for every second that passes, that number increases by 1. We also take a look at the "clearInterval()" function which has the ability to cancel a set-interval.
