Add a conditional statement inside the onreadystatechange event handler that tests to make sure the server has sent back its complete response.
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
};
xhr.open('GET', 'sidebar.html');
xhr.send();
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>AJAX with JavaScript</title>
<script src="app.js"></script>
</head>
<body>
<div id="main">
<h1>AJAX!</h1>
</div>
<div id="sidebar"></div>
</body>
</html>
