How to detect internet speed in JavaScript?

Question

How can I create a JavaScript page that will detect the user’s internet speed and show it on the page? Something like “your internet speed is ??/?? Kb/s”.

thanks to Punit S answer, for detecting dynamic connection speed change, you can use the following code :

navigator.connection.onchange = function () {
 //do what you need to do ,on speed change event
 console.log('Connection Speed Changed');
}
