title: How to update a list of objects in a JSON document
body: <p>I have a JSON document like this:</p>
  
  <pre><code>[
      {"type":"IC","v":88},
      {"type":"SC","v":"XXX"},
      {"type":"IC","v":33},
      {"type":"IC","v":99999}
  ]
  </code></pre>
  
  <p>and I want to replace the value of <code>"v"</code> in each object so the resulted JSON document is like this:</p>
  
  <pre><code>[
      {"type":"IC","v":111},
      {"type":"SC","v":"YYYYYY"},
      {"type":"IC","v":222},
      {"type":"IC","v":333}
  ]
  </code></pre>
  
  <p>I'm wondering if there are some APIs to call to do so?</p>
  
  <p>Thanks!</p>
