title: Reload JS file without page refresh
body: <p>Is there any way, how I can force my browser to refresh (re-download) JS resources only, <strong>without refreshing the whole page?</strong> Solution in any web browser is fine. Of course, browser-independent solution would be the best.</p>
  
  <p>Background:
  Our application has multiple screens on the same page. After some actions on one screen, AJAX fetches another screen. Since the page uses JS a lot, I often need to change its JS resources. After a refresh of the page to get the fixed JS, I have to go through all previous screens before I get to the one that I am currently debugging.</p>
