Unfavourite Tweet button clicker (scrolls through and unlike/unfavourite tweets from your own likes/favourites only)

unfavTimer.js

var unfavTweetsTimer = null;
var doUnfavTweetsFn = () => {
    clearInterval(unfavTweetsTimer);
    Array.from(document.querySelectorAll('article[data-testid="tweet"] div[data-testid="unlike"]'))
    .forEach(unlikeBtn => {
        unlikeBtn.click();
    })
    window.scrollTo({
        top: document.body.scrollHeight,
        left: 0,
        behavior: 'auto'
    });
    unfavTweetsTimer = setInterval(doUnfavTweetsFn, 500);
};
unfavTweetsTimer = setInterval(doUnfavTweetsFn, 16);

Thanks, this is one of the better scripts I've found for this. Still working as of 3/14/23.
