title: Passing "this" after brackets in collection .each() method
body: <p>So I think that <code>this</code> is being passed as a way to be able to maintain the correct reference to <code>this</code> which should be to the View. I'm not sure though. Here is the code. </p>
  
  <pre><code>SomeView = Backbone.View.extend({
  
      getView: function(){
          return this.modelView;
      },
      this.collection.each(function(item){
          var ViewType = this.getModelView(item);
      }, this);
   });
  </code></pre>
  
  <p>So, the last this after the comma is for what? It must be to maintain reference to the correct this but I couldn't find anything that gave a good description of what it was and how it worked. Thanks for any help. </p>
