// See https://www.quora.com/How-do-I-bulk-delete-likes-on-Twitter

inter = setInterval(() => { 
  $("html, body").animate({ 
    scrollTop: $(document).height()-$(window).height(),
    complete: setTimeout(() => {$('.ProfileTweet-action--unfavorite').click().remove()}, 1000) 
  })
  
  if($('.has-more-items').length == 0) { 
    clearInterval(inter)
  }
}, 3000)

// clearInterval(inter) to stop the timer on the scroll-and-unfavourite operation
