The setInterval() method is used evaluate an expression at specified intervals. This function calls function after every duration milliseconds. This goes for unlimited times. Let’s see an example −
It triggers alert(‘Hello’) after every 2000 milliseconds, not only once.
setInterval(function() { alert('Hello');}, 2000);
To clear the usage of setInterval(), use the window.clearInterval() and set the parameter as the ID, like
window.setInterval();
