Aquí está trabajando el código fuente usando el enfoque de función.
<html>
<head>
<style>
.news{padding:10px; margin-top:2px;background-color:red;color:#fff;}
</style>
</head>
<body>
<div id="dd"></div>
<script>
(function(){
var countup = this;
var newNode = document.createElement('div');
newNode.className = 'textNode news content';
newNode.innerHTML = 'this created div contains class while created!!!';
document.getElementById('dd').appendChild(newNode);
})();
</script>
</body>
</html>

Utilice el método .classList.add()
:
const element = document.querySelector('div.foo');
element.classList.add('bar');
console.log(element.className);
<div class="foo"></div>
Este método es mejor que sobrescribir la propiedad className
, porque no elimina otras clases, y no agrega la clase si el elemento ya la tiene.
También puede alternar o eliminar clases usando element.classList
(ver MDN docs).

También existe la forma DOM de hacer esto en JavaScript:
// Create a div and set class
var new_row = document.createElement("div");
new_row.setAttribute("class", "aClassName" );
// Add some text
new_row.appendChild( document.createTextNode("Some text") );
// Add it to the document body
document.body.appendChild( new_row );

También vale la pena echar un vistazo a
var el = document.getElementById('hello');
if(el) {
el.className += el.className ? ' someClass' : 'someClass';
}

var newItem = document.createElement('div');
newItem.style = ('background-color:red');
newItem.className = ('new_class');
newItem.innerHTML = ('<img src="./profitly_files/TimCover1_bigger.jpg" width=50 height=50> some long text with ticker $DDSSD');
var list = document.getElementById('x-auto-1');
list.insertBefore(newItem, list.childNodes[0]);

Esto también funcionará.
$(document.createElement('div')).addClass("form-group")
