Widely available

The value property of the DOMTokenList
interface is a stringifier that returns the value of the list serialized as a
string, or clears and sets the list to the given value.
A string representing the serialized content of the list.
Each item is separated by a space.

<span> element as a DOMTokenList using
Element.classList, then write the value of the list to the
<span>'s Node.textContent.
First, the HTML:
html
<span class="a b c"></span>

js
const span = document.querySelector("span");
const classes = span.classList;
span.textContent = classes.value;
The output looks like this:
