The preview function is not working for me.

When I click on the preview button. it loads a page with index.html file

index.html 
<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>JavaScript Basics</title>
</head>
<body>
  <script src="script.js"></script>
</body>
</html>

that is because for one there is nothing to preview. two the challenge only ask to add the script tags without a source. third the second challenge ask for an alert function within the script tags

<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>JavaScript Basics</title>
</head>
<body>
  <script></script>
</body>
</html>

<!DOCTYPE HTML>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>JavaScript Basics</title>
</head>
<body>
  <script>
    alert('Warning!')
  </script>
</body>
</html>

on the second challenge is when the alert box will pop up when you press the preview button

You're supposed to be just using <script> tags. Then calling the alert function with the text 'Warning'. You won't need the preview function because there isn't any html to load since you're only loading in JavaScript within the <body> tag. Also the script tag is able to accept JS right in between the tags so there's no need to call src="script.js" for this exercise. 

<script>
  alert('Warning');
</script>

Hope this helps.
