title: Does Javascript / jQuery have system vars?
body: <p>I noticed strange issue.</p>
  
  <p>Look at this jQuery:</p>
  
  <pre><code>$(function(){
      status = 1;
      status1 = 2;
  
      $('body').append(status+' - '+status1);
  });
  </code></pre>
  
  <p><a href="http://jsfiddle.net/narekmarkosyan/4JrBK/4/" rel="nofollow">Fiddle</a></p>
  
  <p>As you can see output is:</p>
  
  <pre><code>- 2
  </code></pre>
  
  <p>So <code>status</code> is system var for JavaScript or jQuery?</p>
  
  <p>And is there any other vars like this?</p>
