But, in answer to the original question, consider something as a simple as an upvote: javascript can notify the server and tweak a text string in the page. The alternative is waiting for the server to rebuild the page (with any subsequent changes because it didn't record the state of the page when you fetched it) and then transmit it wholesale back to you, and then the browser then flickers because it's not the same page and the browser doesn't attempt to work out whether there are tiny changes or it's a 100% different.
