A number.
Given a video element with the ID "myVideo":
js
const v = document.getElementById("myVideo"); const buf = v.buffered; const numRanges = buf.length; if (buf.length === 1) { // Only one range if (buf.start(0) === 0 && buf.end(0) === v.duration) { // The one range starts at the beginning and ends at // the end of the video, so the whole thing is loaded } }
This example looks at the time ranges and looks to see if the entire video has been loaded.
