This script prompts for the number of videos to process and then console.logs all the video titles found

youtubevideoslist.js

// Get all video elements on the page
const videoElements = document.querySelectorAll('a#video-title-link');

// Ask user for the number of videos to process
const numberOfVideos = parseInt(prompt("How many videos do you want to process?"), 10);

// Initialize an empty string to store all video lines
let videoList = '';

// Process the required number of video titles
for (let i = 0; i < Math.min(numberOfVideos, videoElements.length); i++) {
    const video = videoElements[i];
    const title = video.getAttribute('title');
    const link = 'https://youtube.com' + video.getAttribute('href');
    videoList += `${i + 1}. <a href="${link}">${title}</a>\n`;
}

// Log the entire list in a single console.log
console.log(videoList);
