A number representing the start time, in seconds.

) is created starting at 0.1 second and ending at 0.9 seconds. The startTime
property is then printed to the console.
js
let video = document.querySelector("video"); let track = video.addTextTrack("captions", "Captions", "en"); track.mode = "showing"; let cue1 = new VTTCue(0.1, 0.9, "Hildy!"); console.log(cue1.startTime); // 0.1 track.addCue(cue1);
