Как удалить атрибут на JS Pure?

var newsBlock = document.getElementsByClassName("newsBlock"); 
 
 for (var i = 0; i < newsBlock.length; i++) { 
   newsBlock[i].removeAttribute("title"); 
 }

.newsBlock { 
  border: 1px solid #000; 
  margin-bottom: 10px; 
  width: 100px; 
  text-align: center; 
}

<div class="newsBlock" title="block">My block</div> 
<div class="newsBlock" title="block">My block</div> 
<div class="newsBlock" title="block">My block</div> 
<div class="newsBlock" title="block">My block</div>
