Thanks! here is my clojurescript equivalent (in #"" regex literal)

(defn parse-youtube [url]
  (let [host-re #"(vi/|v=|/v/|youtu.be/|/embed/)"
        key-re #"(?i)[^0-9a-z_-]"
        parts (str/split url host-re)]
    (if (< (count parts) 2)
      (parts 0)
      ((str/split (parts 2) key-re) 0))))

(comment
  (let [examples ["https://music.youtube.com/watch?v=6qg4EuEjDuQ"
                  "http://youtu.be/Ab25nviakcw"
                  "https://www.youtube.com/watch?feature=g-vrec&v=Y1xs_xPb46M"
                  "http://i1.ytimg.com/vi/Ab25nviakcw/default.jpg"
                  "BGL22PTIOAM"]]
    (map parse-youtube examples)))

It works for all the cases. +1!! Thanks @takien

The code has unexpected results when i provide it with a link that is not one of the valid youtube domains, e.g. the link https://ssssssssss?v=OoY9gyXTuD8 return OoY9gyXTuD8 which is not correct. FYI.

might wanna add a |\/shorts\/| to the split regex to catch the newer format too, e.g. https://www.youtube.com/shorts/RGoMN6my_JA

I found a better RegExp which includes YouTube shorts also:
/^.*(?:(?:youtu\.be\/|v\/|vi\/|u\/\w\/|embed\/|shorts\/)|(?:(?:watch)?\?v(?:i)?=|\&v(?:i)?=))([^#\&\?]*).*/

Try to check these use-cases by e.g. JEST:

let urls = [
    {test: 'https://www.youtube.com/shorts/5r7QeUnpLKE?feature=share', expected: "5r7QeUnpLKE"},

let i = 0;
test('Test for ' + urls[i], ()={
    let youTubeId = YouTubeGetID(urls[i].test);
    expect(youTubeId).toBe(urls[i].expected);
});

/* (*) "" or false or undefined ...  */

Thanks for your work for my first try
🙂

worked best for me (in typescript):

export const youTubeGetID = (url: string) => {
    const [a, , b] = url.replace(/(>|<)/gi, '').split(/^.*(?:(?:youtu\.?be(\.com)?\/|v\/|vi\/|u\/\w\/|embed\/|shorts\/)|(?:(?:watch)?\?v(?:i)?=|\&v(?:i)?=))([^#\&\?]*).*/)
    if (b !== undefined) {
        return b.split(/[^0-9a-z_-]/i)[0]
    } else {
        return a
    }
}
