title: How to check if an object contains another object?
body: <pre><code>var person = {
         "name" : "Bronn",
         "description" : {
            "occupation" : "guardian knight",
            "age" : 52
         }
      }
  
  for(var key in person){
     if(person[key] == /*contains json object */){
        //do something
     }
  }
  </code></pre>
  
  <p>I want to loop this person and check if its value contains single data or another object.</p>
