To update the content of the paragraph, we'll need to access it.

Put together the instruction to find the paragraph by its ID, "username".

<html>
<body>
  <p id="name">JohnnyG</p>
  <p id="age">25</p>
  <button onclick="generate()">Generate a username</button>
  <p id="username"></p>
  <script src="script.js"></script>
</body>
</html>
]]>

Make sure to assemble document.getElementById("username").innerHTML.
