Why does the Google Analytics script I add to my webpage need to come in two script blocks?

<script type='text/javascript'>     var gaJsHost = (('https:' == document.location.protocol) ? 'https://ssl.' : 'http://www.');     document.write(unescape('%3Cscript src='' + gaJsHost + 'google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E')); </script> <script type='text/javascript'>     try {         var pageTracker = _gat._getTracker('UA-xxxxxxx-xx');         pageTracker._trackPageview();     } catch (err) { }  </script>

  1. The first script in your quote above writes a new <script> loading tag into the document. The second block has dependencies that are loaded by that dynamically written script tag, so the browser has to have a chance to load and parse the script before the second block runs. If everything was in one block, the script loading wouldn’t take place until the first script section ended.
