The document.createTextNode() method creates a text node without wrapping it in an HTML tag. It’s useful when you want to add plain text to an element without altering its structure.

let textNode = document.createTextNode('Dxrkd3v was here');

Example of inserting text into a paragraph using pure JS without modifying the HTML:

let p = document.createElement('p');  
let t = document.createTextNode('Hello, Cxd3!');  

p.appendChild(t);  
document.body.appendChild(p); 

This method also lets you change text on the fly:

let div = document.getElementById('h1');  
div.appendChild(document.createTextNode('New h1!'));  

createTextNode() is a cool way to add text without touching the document’s structure. It gives you precise control over content while preserving the existing HTML.
