<h2>JavaScript Errors</h2>
<p>In this example we have written "alert" as "adddlert" to deliberately produce an error.</p>
<p>The name property of the Error object returns the name of the error and the message property returns a description of the error:</p>
<p id="demo" style="color:red"></p>
<script>
try {
  adddlert("Welcome guest!");
}
catch(err) {
  document.getElementById("demo").innerHTML = 
  err.name + "<br>" + err.message;
}
</script>
</body>
