Hey Muhammad~

Check to see where you've linked your script in the HTML file. If the script is inserted above the h1 elements then it is loaded before they are and it won't be able to interact with them. Moving your script tag towards the bottom will solve this:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>JavaScript Basics</title>
    <link href="css/style.css" rel="stylesheet">
    </head>
  <body>
    <main>
      <h1>Hello, JavaScript!</h1>
    </main>
    <script src="js/preview.js"></script>
  </body>
</html>
