entries()
Return value
Returns an iterator

Examples
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 key/value
pairs using entries()
, then iterate through each one using a
for...of
loop, writing them 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.entries();
for (const value of iterator) {
span.textContent += `(${value})`;
}
The output looks like this:
