TextTrackCue

The TextTrackCue interface of the WebVTT API is the abstract base class for the various derived cue types, such as VTTCue and DataCue; you will work with these derived types rather than the base class.

These cues represent strings of text presented for some duration of time during the performance of a TextTrack. The cue includes the start time (the time at which the text will be displayed) and the end time (the time at which it will be removed from the display), as well as other information.
