AJAX and XMLHttpRequest Object 

That's right....this is because, in the event handler function of load event, we are using addAdjacentHTML method which will add a new HTML content without replacing the existing content. So, it is appending the new HTML content after the text content 'Loading...' To resolve this, in the event handler function of load event, at the beginning you can set the innerHTML property of div to empty string div.innerHTML = ''; you can write rest of the logic of this event handler function after above statement.
