Delete all "Watch later" videos

readme.md

It's semi-automated at worse, automated at best

open browser

open inspector on console

copy paste, enter

wait

if nothing is deleted, might be a timeout from youtube, refresh page, back step 1

until completion

Eventually Youtube won't re-load automatically your Watch Later videos, so you might have to refresh the page.

When you have the 5k rows, you might have to do it multiple times.

Some videos might be deleted or in private, you have an option on the three dots "burger" menu to toggle them.

It will take you a while, the browser need to stay active otherwise the code of YT won't refresh the video list and sometimes it just doesn't, so you will have to refresh and re-execute.

Happy deletion!
