Challenge Task 1 of 1

On line 2 of the app.js file, add an onreadystatechange event handler. Add an anonymous function, but don't put any code inside it. Bummer! There was an error with your code: SyntaxError: Parse error

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

}
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>
