title: Backbone class properties? 'this.property' won't work in it's methods?
body: <p>Help with Backbone needed:</p>
  
  <pre><code>var Vehicles = Backbone.Model.extend({}, {
      name: 'Sabre',
      summary: function() {
          console.log(this.name +" is a dog!");
      }
  });
  
  Vehicles.summary();
  </code></pre>
  
  <p>This prints out: " is a dog"</p>
  
  <p>Two questions:</p>
  
  <ol>
  <li><p>Why doesn't it print out the name? Why doesn't <strong>this.name</strong> work? </p></li>
  <li><p>On the following line, what is the difference between <strong>firstBlock</strong> and <strong>secondBlock</strong>?</p>
  
  <pre><code>Backbone.Model.extend({firstBlock},{SecondBlock});
  </code></pre></li>
  </ol>
