We when retrieve an iterator containing the values using values() , then iterate through those values using a for ... of loop, writing each one to the <span> 's Node.textContent .

First, the HTML:

<span class="a b c"></span>
					

Now the JavaScript:

var span = document.querySelector("span");
var classes = span.classList;
var iterator = classes.values();
for(var value of iterator) {
  span.textContent += value + ' ++ ';
}
