On ready state change function

This is not passing and I dont know why.

var xhr = new XMLHttpRequest(); xhr.onreadystatechange = function (){

}); xhr.open('GET', 'sidebar.html'); xhr.send();

app.js 
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function (){

});
xhr.open('GET', 'sidebar.html');
xhr.send();
index.html 
<!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>
