title: is GA using arrays as associative?
body: <pre><code>_gaq.push(['_setDomainName', '.mydomain.com']);
  </code></pre>
  
  <p>I'm confused here, is GA pushing two new elements onto _gaq array or is this an associative key-value pair being pushed onto _gaq?</p>
  
  <p>I'm just trying to understand JS better</p>
