Question

What problems can be caused by placing comments in a script tag calling an external script? My coworker told me this is not a good practice.

Something like this:

<script src="http://jqueryjs.googlecode.com/files/jquery-1.2.6.min.js" type="text/javascript">
            //    import jQuery
            //    cdn refers to a remotely hosted library
</script>

Answer 1

Maybe your coworker is concerned you’ll get in the habit of doing this

<script src="http://jqueryjs.googlecode.com/files/jquery-1.2.6.min.js" type="text/javascript">
            //    import jQuery
            //    cdn refers to a remotely hosted library
</script>

And then eventually struggle to figure out why this doesn’t work

<script src="http://jqueryjs.googlecode.com/files/jquery-1.2.6.min.js" type="text/javascript">
     $(document).ready(function() {
           $('#ActionButton').click(DoAction);
     });
</script>

Because you’ve developed a bad habit
