Examples

Using addEventListener():

const videoElement = document.querySelector('video');
videoElement.audioTracks.addEventListener('change', (event) => {
    console.log(`'${event.type}' event fired`);
});

// changing the value of `enabled` will trigger the `change` event
const toggleTrackButton = document.querySelector('.toggle-track');
toggleTrackButton.addEventListener('click', () => {
  const track = videoElement.audioTracks[0];
  track.enabled = !track.enabled;
});

Using the onchange event handler property:

const videoElement = document.querySelector('video');
videoElement.audioTracks.onchange = (event) => {
    console.log(`'${event.type}' event fired`);
};

// changing the value of `enabled` will trigger the `change` event
const toggleTrackButton = document.querySelector('.toggle-track');
toggleTrackButton.addEventListener('click', () => {
  const track = videoElement.audioTracks[0];
  track.enabled = !track.enabled;
});
