Two things. (1) You're missing the opening html tag, and (2) your JavaScript is being processed before the button is loaded. Modified html is below:

 <!Doctype html>
<html>
   <body> <h1 id="myHeading">Java</h1>
      <button id="myButton">Change Heading Color</button>
      <script src="dom.js"></script>
   </body>
</html>
