title: jQuery ajax() URL is required?
body: <p>the <a href="http://api.jquery.com/jQuery.ajax/#jQuery-ajax-url-settings" rel="nofollow noreferrer">ajax function's</a> header is: <code>jQuery.ajax( url [, settings ] )</code></p>
  
  <p>With the documentation saying that URL is required, why in the examples is only 'settings' supplied?</p>
  
  <pre><code>$.ajax({
    type: "GET",
    url: "test.js",
    dataType: "script"
  });
  </code></pre>
