// HOW TO USE:
// 0. Get OAuth from https://developers.google.com/youtube/registering_an_application
// 1. Go to https://www.youtube.com/feed/library
// 2. Paste snippet below in DevTools
// 3. Replace `VIDEOS` with copied data
// 4. Run script

// JSON.stringify(
//   Array.from(document.querySelectorAll("a.ytd-playlist-video-renderer"))
//     .map((v) => {
//       const time = v
//         .querySelector("span.ytd-thumbnail-overlay-time-status-renderer")
//         .getAttribute("aria-label");
//       const hoursMatch = time.match(/(\d+) hour/);
//       const hours = parseInt((hoursMatch && hoursMatch[1]) || 0, 10);
//       const minutesMatch = time.match(/(\d+) minute/);
//       const minutes = parseInt((minutesMatch && minutesMatch[1]) || 0, 10);
//       const secondsMatch = time.match(/(\d+) second/);
//       const seconds = parseInt((secondsMatch && secondsMatch[1]) || 0, 10);
//       let url = new URL(v.href);
//       return {
//         id: url.searchParams.get("v"),
//         length: seconds + minutes * 60 + hours * 60 * 60,
//       };
//     })
//     .sort((a, b) => a.length - b.length)
