title: Print a custom object on console in extjs
body: <p>I am trying my hands on extjs 4.2.2 on a UI development. I am totally new to this. I am unable to understand how to print the objects for which i dont know the properties. Can someone please help me out in this.</p>
  
  <p>If i know the property of the object i can do it as below.</p>
  
  <pre><code>console.log('print: ' + myObj.get('name'));
  </code></pre>
  
  <p>But if i dont know the property(in this case name) how can get to print it? Is there any way of iterating the object properties and print it. Kindly help me on this.</p>
