title: Does jQuery have a hashtable type mutable data structure?
body: <p>Pseudo-code is probably the best way to show what I'm looking to do in jQuery:</p>
  
  <pre><code>$(selector).each(function() {
      // pull data from LI tags or whatever, store in variables (imgURL, tagline, summary)
      $someDataStructure.add({imgURL, tagline, summary});
  });
  </code></pre>
  
  <p>Then later... reference the structure</p>
  
  <pre><code> $someDataStructure.each(function() {
       var x = $someDataStructure['imgURL'];
       // etc.
   });
  </code></pre>
  
  <p>Any suggestions on how I could go about doing this?</p>
