title: What Javascript event fires when async resources are finished loading?
body: <p>If I load a script asynchronously like this</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
      (function () {
          var js = document.createElement('script');
          js.type = 'text/javascript';
          js.async = true;
          js.src = '&lt;%=BundleTable.ResolveUrl("~/js") %&gt;';
          var s = document.getElementsByTagName('script')[0];
          s.parentNode.insertBefore(js, s);
      })();
  &lt;/script&gt;
  </code></pre>
  
  <p>what event fires once the async stuff is finished loading and the dom is finished loading?</p>
