SCRIPT:
// Get a reference to the element in which we want to insert a new node
var parentElement = document.getElementById('parentElement');

for(var i = 1; i < 5; i++) {
    // Get a reference to the first child
    var theFirstChild = parentElement.firstChild;
 
    // Create a new element
    var newElement = document.createElement("div");
    var txtElement = document.createTextNode("Hello " + i);
 
    newElement.appendChild(txtElement);

    // Insert the new element before the first child
    parentElement.insertBefore(newElement, theFirstChild);
