title: Using global variables in backbone.js .. best practice
body: <p>Maybe is just a stupid question.<br>
  In all examples I have seen the view model and collections are global variables.<br>
  Here an exmaple. <a href="http://www.joezimjs.com/javascript/introduction-to-backbone-js-part-1-models-video-tutorial/" rel="nofollow">introduction-to-backbone</a>.<br>
  It will be possible to define model view and collection without using global variables or namespace?<br>
  And then how can I access them? </p>
