title: Google Analytics tracking script remarks/review
body: <p>I was looking at the script Google provides you when you want to use Google Analytics. </p>
  
  <p>If you look at the IIF you see it requires 7 arguments, but there are only 5 parameters passed.</p>
  
  <pre><code>(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','https://www.google-analytics.com/analytics.js','ga');
  
  ga('create', 'trackingid', 'auto');
  ga('send', 'pageview');
  </code></pre>
  
  <p>They make a nice isogram of the arguments, and this won't break in Javascript, but aren't the 'a' and 'm' arguments obsolete?</p>
  
  <p>I guess the '1 * new Date()' is also a bad practice and getTime would be much nicer. But they probably do this for browser-support. Although getTime is widely supported.</p>
