title: appending to json file in javascript
body: <p>I have a json file, employees.json, that I would like to append data to this object.
  The file looks like this:</p>
  
  <pre><code>var txt = '{"employees":[' +
  '{"firstName":"Jerry","lastName":"Negrell","time":"9:15 am","email":"jerry@bah.com","phone":"800-597-9405","image":"images/jerry.jpg" },' +
  '{"firstName":"Ed","lastName":"Snide","time":"9:00 am","email":"edward@bah.com","phone":"800-597-9406","image":"images/ed.jpg" },' +
  '{"firstName":"Pattabhi","lastName":"Nunn","time":"10:15 am","email":"pattabhi@bah.com","phone":"800-597-9407","image":"images/pattabhi.jpg" }'+
  ']}';
  </code></pre>
  
  <p>I would like to append:</p>
  
  <ul>
  <li>firstName:Mike</li>
  <li>lastName:Rut</li>
  <li>time:10:00 am</li>
  <li>email:rut@bah.com</li>
  <li>phone:800-888-8888</li>
  <li>image:images/mike.jpg</li>
  </ul>
  
  <p>to employee.json.</p>
  
  <p>How would I accomplish this?</p>
