title: Google Analytics Code Explanation
body: <p>Can someone explain this code 'step by step','line by line'?
  I would like to learn more about Asynch code and how Google loads their script, how to
  'hide' javascrippt from users (I know that I can't hide it but
  at least make it something like Google does, not to show all code in one file)</p>
  
  <pre><code>&lt;script&gt;
    (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
    (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
    m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
    })(window,document,'script','//www.google-analytics.com/analytics.js','ga');
  
    ga('create', 'UA-xxxxxxxx-x', 'xxxxxx.com');
    ga('send', 'pageview');
  &lt;/script&gt;
  </code></pre>
