I am new to Java Script. In the below code I am trying to create an error intentionally to learn how try...catch works. But nothing is running. 

<html>
<body>
<p id="demo"></p>
<script>
try {
    adddlert("Hi User!");
}
catch(Error e) {
    document.getElementById("demo").innerHTML = e.message;
}
</script>
</body>
</html>

What I am missing?

Reset to default 6 

try {
    adddlert("Hi User!");
}
catch(e) {
    document.getElementById("demo").innerHTML = e.message;
}
<html>
<body>
<p id="demo"></p>
</body>
</html>

Syntax Error:

Change your catch (Error e) as catch (e).
