title: Why does Chrome & FireFox console print 'undefined'?
body: <p>Take this simple Test object and paste it into the console. You'll see that it says <code>undefined</code>. The object is working because it also prints <code>123</code>, but what is the <code>undefined</code> about?</p>
  <p><strong>Test:</strong></p>
  <pre><code>var Test = new (function(){
      return {
          get testing(){
              return &quot;123&quot;;
          }
      }
  });
  
  console.log(Test.testing);
  </code></pre>
  <p><strong>Console Output:</strong></p>
  <pre><code>123
  undefined
  </code></pre>
