title: Why object.[[Prototype]] does not work in Chrome Developer Tools?
body: <p>I'm trying to do call the <code>[[Prototype]]</code> method of an object, by using this tutorial, from Mozilla (<a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Inheritance_and_the_prototype_chain" rel="nofollow noreferrer">https://developer.mozilla.org/en-US/docs/Web/JavaScript/Inheritance_and_the_prototype_chain</a>), but it does not seem to work.</p>
  
  <p>Does anyone knows why?</p>
  
  <p>Thanks,</p>
  
  <p>Some code:</p>
  
  <pre><code>function Graph() {
    this.vertices = [];
    this.edges = [];
  }
  
  Graph.prototype = {
    addVertex: function(v) {
      this.vertices.push(v);
    }
  };
  
  var g = new Graph();
  g.[[Prototype]];
  </code></pre>
