HTMLMediaElement: ratechange event

The ratechange event is fired when the playback rate has changed.

These examples add an event listener for the HTMLMediaElement's ratechange event, then post a message when that event handler has reacted to the event firing.

Using addEventListener():

const video = document.querySelector('video');

video.addEventListener('ratechange', (event) => {
  console.log('The playback rate changed.');
});

Using the onratechange event handler property:

const video = document.querySelector('video');

video.onratechange = (event) => {
  console.log('The playback rate changed.');
};
