title: Sorting strings in reverse order with backbone.js
body: <p>I'm trying to sort a Backbone.js collection in reverse order. There are previous replies on how to do this with integers, but none with strings.</p>
  
  <pre><code>var Chapter  = Backbone.Model;
  var chapters = new Backbone.Collection;
  
  chapters.comparator = function(chapter) {
    return chapter.get("title");
  };
  
  chapters.add(new Chapter({page: 9, title: "The End"}));
  chapters.add(new Chapter({page: 5, title: "The Middle"}));
  chapters.add(new Chapter({page: 1, title: "The Beginning"}));
  
  alert(chapters.pluck('title'));
  </code></pre>
  
  <p>The above code sorts the chapters <strong>from A -> Z</strong>, but how do I write a comparator that sorts it <strong>from Z -> A</strong>?</p>
