title: how to change json object name (key)?
body: <p>Just a quick question:</p>
  
  <p>If I have a json object which contains "key/value"s like this:</p>
  
  <pre><code>"name":"value"
  </code></pre>
  
  <p>and I want to change the name parts to something else, what should I do? I don't want to remove and make it again.</p>
