  <p>and I have this JSON</p>
  
  <pre><code>{"computers":[{"id":"7bc530","name":"Dell","description":"Dell"},
  {"id":"f30ef","name":"HP","description":"HP"},
  {"id":"9e6d","name":"Compaq","description":"Compaq"},
  {"id":"4d8665a3","name":"Toshiba","description":"Toshiba"},
  {"id":"4fe1457","name":"Asus","description":"Asus"},
  {"id":"4a18d27","name":"Acer","description":"Acer"}]}
  </code></pre>
  
  <p>I want to replace the "serial" element in the first JSON with the "Description" in this one. The reason why I need it in one JSON is that I am using a DataTable and I can only pass one JSON in. </p>
  
  <p>I'm not sure how I can do this in Javascript / JQuery?</p>
