title: Backbone.js - passing arguments through constructors
body: <p><strong>Scenario:</strong><br>
  I got an <code>alert()</code> saying <code>undefined</code> when I (try to) set the <code>myVar</code> variable through the Constructor. However if I uncomment the <code>myVar</code> that's living inside the myView, the alert then instead says "Hello from inside", just as one would expect.</p>
  
  <p><strong>Question:</strong><br>
  Does this mean that I cannot set any params in the constructor of the view except backbones own params, such as <code>model</code>, <code>collection</code>, <code>el</code>, <code>id</code>, <code>className</code> &amp; <code>tagName</code>?<br>

  <p><strong>The code:</strong></p>
  
  <pre><code>var myView = Backbone.View.extend({
  
      //myVar : 'Hello from inside',
  
      initialize: function() {
          alert(this.myVar);
      }
  )};
  
  new myView({myVar: 'Hello from outside'});
  </code></pre>
