var seekable = audioOrVideo.seekable;


A TimeRanges object.


var video = document.querySelector("video");
var timeRangesObject = video.seekable;
var timeRanges = [];
//Go through the object and output an array
for (let count = 0; count < timeRangesObject.length; count ++) {
    timeRanges.push([timeRangesObject.start(count), timeRangesObject.end(count)]);
