title: Javascript default keyword
body: <p>I'm using some existing code and there is this line I don't understand. I only know that default can be used as part of a swtich statement, but didn't know if there is some other use for it.  The code works. It's part of TurkIt which is used for running programs through Amazon's MTurk.</p>
  
  <pre><code>function getQuestion(numA, numB) {
      default xml namespace = "http://mechanicalturk.amazonaws.com/AWSMechanicalTurkDataSchemas/2005-10-01/QuestionForm.xsd";
      var q = &lt;QuestionForm&gt; ...
  </code></pre>
  
  <p>See the <code>default</code> before the <code>xml namespace</code> statement.</p>
