The values() method of the DOMTokenList interface returns an iterator allowing the caller to go through all values contained in the DOMTokenList. The individual values are strings.

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:
