DOMTokenList: values() method

None.

Returns an iterator.

In the following example we retrieve the list of classes set on a <span> element as a DOMTokenList using Element.classList. 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:

const span = document.querySelector("span");
const classes = span.classList;
const iterator = classes.values();

for (const value of iterator) {
  span.textContent += `(${value}) `;
}

The output looks like this:
