How to search a text through multiple urls-CodePudding

Ok so i've been struggling with this one for some time and can't seem to figure out how to do it. I wanted to do a test with a bunch of youtube Urls i generated using a random string, basically i goes "https://www.youtube.com/watch?v=XXX" XXX meaning the randomly generated sequence.

What i wanted to try was to differentiate the Urls between the "this video isn't available" from the ones that do work.

But i can't seem to find anywhere on the internet how to run a code that will go through the Urls and tell you which one contains the certain text from the others.

It seems to be a task that requires javascript but i'm not sure how i can use it to meet it.

For now i've been doing it hand to hand double clicking using Notepad but it's so tiring for my wrists lol.

Could you do something like this? And then once you invoke the function just catch the error if thrown and output the ids were applicable?

import fs from "fs";
import ytdl from "ytdl-core";

/**
 * @description Download a youtube video to a file for a given video id.
 * @param {string} videoId The youtube video id.
 * @param {string} outputPath The path to the output file.
 * @returns {Promise<void>}
 * @example downloadVideo("videoId", "outputPath");
 */
export async function downloadVideo(
  videoId: string,
  outputPath: string
): Promise<void> {
  const video = await ytdl(videoId);
  const writeStream = fs.createWriteStream(outputPath);
  video.pipe(writeStream);
}

/**
 * @description Generate a list of random video ids
 * @param {number} count The number of video ids to generate.
 * @returns {string[]}
 * @example generateVideoIds(10);
 */
function generateVideoIds(count: number): string[] {
  const videoIds: string[] = [];

  for (let i = 0; i < count; i  ) {
    const videoId = Math.random().toString(36).substring(2, 15);
    videoIds.push(videoId);
  }

  return videoIds;
}

Wouldn't this be better to use the YouTube API?
