CREATE A TIMING EVENT IN HTML

  one of the most cooler things most programmer have thought of is how to create a simple timing event how to make ads appear at some interval in your page how to make a certain picture pop out after spending some time on a o page today am going to teach you how to create a timing event using javascript with a simple example

     The window object allows execution of code at specified time intervals.

These time intervals are called timing events.

The two key methods to use with JavaScript are:

setTimeout(function, milliseconds)
Executes a function, after waiting a specified number of milliseconds.
setInterval(function, milliseconds)
Same as setTimeout(), but repeats the execution of the function continuously.

below is a simple that displays a digital watch after 5seconds of page opening

<!DOCTYPE html>
<html>
<body>

<p>welcome</p>

<p id="demo"></p>

<script>
var myVar = setInterval(myTimer, 5000);

function myTimer() {
    var d = new Date();
    document.getElementById("demo").innerHTML = d.toLocaleTimeString();



}
</script>

</body>
</html>
when writing you script you start by creating and setting  a time interval for the funtion in your script to run
var myVar = setInterval(myTimer, 5000); this is five seconds since time is measured in milliseconds
then add a function that does whatever you want in javascript in this case a digital time
