Display last modified time of JavaScript file
<p>I am developing a webapp and the browser doesn't consistently empty the cache each time I refresh, so sometimes I'm not getting the latest version of my JavaScript file loaded.</p>

<p>I would like to have a console message indicating if I'm using the latest version of the JavaScript file each time I refresh. I'm thinking that displaying the "last modified" time of the JavaScript file will do the job!</p>

<p>Any thoughts? Is there a standard solution to my problem that I've missed?</p>
