Javascript: Call a function after specific time period

You can use JavaScript Timing Events to call function after certain interval of time:

This shows the alert box every 3 seconds:

setInterval(function(){alert("Hello")},3000);

You can use two method of time event in javascript.i.e.

  1. setInterval(): executes a function, over and over again, at
    specified time intervals
  2. setTimeout() : executes a function, once, after waiting a
    specified number of milliseconds
