Как удалить div по клику на кнопку в нем?

function remove(){ 
  let w = this.closest('.form'), br = w.nextElementSibling; 
   
  if(br.nodeType === 1 && br.nodeName === 'BR') 
    br.remove(); 
   
  w.remove(); 
} 
 
Array.from(document.querySelectorAll('.del')).forEach(b => b.addEventListener('click', remove)); 
 
/* 
jQuery style: 
 
$('.del').on('click', function(){ 
  $(this).parent('.form').remove(); 
}); 
*/
