Definition and Usage
The timeupdate event occurs when the playing position of an audio/video has
changed.
This event is invoked by:
- Playing the audio/video
- Moving the playback position (like when the user fast forwards to a
different point in the audio/video)
Tip: This timeupdate event is often used together with the
currentTime property of the Audio/Video Object,
which returns the current
position of the audio/video playback, in seconds.
