title: How do I add JSON object as new level to another JSON object?
body: <p>I have a code that gets in the end collection of two JSON objects, something like this. </p>
  
  <pre><code>var jsonL1 = {"holder1": {}}
  var jsonL2 = {"section":"0 6","date":"11/12/13"}
  </code></pre>
  
  <p>I would like to insert jsonL2 inside jsonL1.holder1 and merge it to one JSON object. </p>
  
  <p>Desired output</p>
  
  <pre><code>{
      "holder1": {
          "section": "0 6",
          "date": "11/12/13"
      }
  }
  </code></pre>
  
  <p>How can I do that?</p>
