JavaScript external script alert() function not working

Question

I have something simple. I have an html file and JavaScript file. In the JavaScript file the simple alert() function is called but, it does not work!

I wrote a second line in the JavaScript file to make sure I was not giving the incorrect path console.log() and it works as expected.

HTML:

<!doctype html>
<html>
<head>
    <meta charset="utf-8">
    <title>Demo</title>
</head>
<body>

    <div id="container">

    </div>

    <script src="functionality.js"></script>
</body>
</html>

In external JavaScript file:

alert('hello'); // does not get executed
console.log( 'hello' ); // gets executed

Why this does not work?

There is no visible reason why it should not work. Any message in the console? Perhaps you have suppressed alerts in the browser? — mplungjan, Jul 19 '15 at 20:12
Using Chrome? Have you pressed "prevent this page from creating additional dialoug" recently? Try restarting the browser. — Tholle, Jul 19 '15 at 20:15

You have probably pressed "prevent this page from creating additional dialog" in your Chrome browser. Try restarting it.
