Script to remove all videos from Youtube Watch Later playlist

Remove videos from Youtube Watch Later playlist.md

UPDATED 22.11.2022

It's been two years since the last update, so here's the updated working script as per the comments below.

Thanks to BryanHaley for this.

setInterval(function () {
    video = document.getElementsByTagName('ytd-playlist-video-renderer')[0];

    video.querySelector('#primary button[aria-label="Action menu"]').click();

    var things = document.evaluate(
        '//span[contains(text(),"Remove from")]',
        document,
        null,
        XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
        null
    );

    for (var i = 0; i < things.snapshotLength; i++) 
    {
        things.snapshotItem(i).click();
    }
}, 500);

Non-english users will need to change "Action menu" and "Remove from" to what YouTube uses for their localization.

I made an attempt before looking at the solutions here. For posterity's sake, here is my basic solution:

setInterval(function () {
    document.getElementsByTagName("ytd-playlist-video-renderer")[0].querySelector("button").click();
    setTimeout((() => document.querySelectorAll("ytd-menu-service-item-renderer")[2].click()), 500)
}, 1800);

I changed the array access to only delete old stuff, so it would make more sense to use document.getElementByTagName if you're deleting everything, but I might as well keep it for later modification.
