In jQuery what does...... var myVar = $( [] ); ......do?
<pre><code>var myVar = $( [] );
</code></pre>

<p>What does this jQuery do? </p>

<p>Does it initialize the variable to an empty jQuery set? I have searched the jQuery docs but haven't found an explaination for this syntax.</p>

  <p>Excerpt from the jQuery docs <a href="http://api.jquery.com/jQuery/" rel="nofollow">http://api.jquery.com/jQuery/</a>  </p>
  
  <p>Returning an Empty Set   -   </p>
  
  <p>As of jQuery 1.4, calling the jQuery() method with no arguments returns an empty jQuery set (with a length property of 0). In previous versions of jQuery, this would return a set containing the document node.</p>

<p>So could <code>$( [] )</code> be a legacy method for returning an empty jQuery set or does it do something entirely different?</p>
