The data property of the CharacterData interface represent the value of the current object's data.

A string with the character information contained in the CharacterData node.

Note: CharacterData is an abstract interface. The examples below use two concrete interfaces implementing it, Text and Comment.

<!-- This is an HTML comment !-->
<output id="Result"></output>

let comment = document.body.childNodes[1];
let output = document.getElementById("Result");

output.value = comment.data;

<span>Result: </span>Not set.

let span = document.getElementsByTagName("span")[0];
let textnode = span.nextSibling;

textnode.data = "This text has been set using textnode.data."
