<script>!window.jQuery && document.write(unescape('%3Cscript src="javascripts/jquery-1.8.2.min.js"%3E%3C/script%3E'))</script>

Answer 1

Do it like this:

<script src="//cdnjs.cloudflare.com/ajax/libs/jquery-timeago/0.11.4/jquery.timeago.js"></script>
<script>!$.fn.timeago && document.write(unescape('%3Cscript src="javascripts/jquery.timeago.js"%3E%3C/script%3E'))</script>

The strategy is actually the same, the way to check for jQuery module is using $.fn.pluginName.
