After we retrieve it, we can update it by using the = sign followed by a new value like "No Messages".

<html>
<body>
  <h3>Tweeter</h3>
  <p id="messages">New Messages</p>
  <script>
   document.getElementById("messages").innerHTML = "No Messages";
  </script>
</body>
</html>]]>

Make sure to pick =, followed by "No Messages".
