title: Iterating objects with underscore.js
body: <p>So, I am learning out backbone.js and are currently iterating over some models in a view with the below example. The first snippet works, when the other underscore.js-based one doesn't. Why?</p>
  
  <pre><code>// 1: Working
  this.collection.each(function(model){ console.log(model.get("description")); });
  
  // 2: Not working       
  _.each(this.collection, function(model){ console.log(model.get("description")); });
  </code></pre>
  
  <p>What am I doing wrong, as I can't see it by myself?</p>
