title: clone an object's element and push to it's self
body: <p>I have a object  A.</p>
  
  <p>if I <code>JSON.stringify(A)</code>, I get this result:</p>
  
  <pre><code>{
      "OrderA": [{
          "orderId": "19",
          "serverId": 129,
          "description": "Apple",
          "status": "1",
          "details": ""
      }]
  }
  </code></pre>
  
  <p>Now, I would like to clone it's own element and make a larger object like this:</p>
  
  <pre><code>{
      "OrderA": [{
          "orderId": "19",
          "serverId": 129,
          "description": "Apple",
          "status": "1",
          "details": ""
      }],
      "OrderA": [{
          "orderId": "19",
          "serverId": 129,
          "description": "Apple",
          "status": "1",
          "details": ""
      }],
       "OrderA": [{
          "orderId": "19",
          "serverId": 129,
          "description": "Apple",
          "status": "1",
          "details": ""
      }]
  }
  </code></pre>
  
  <p>How to achieve this by using lodash/underscore/ or jQuery?</p>
  
  <p>so far, I've tried jQuery.extend, lodash union, and didn't work.</p>
