title: Add/Remove elements in a JSON Array in Scala/Play
body: <p>I have a pretty complex JSON object that contains, among other things, some JSON arrays that I need to update, removing and adding elements.
  To do that I'm trying to use a JsPath that point directly to the object inside the array that I need to remove, something like:</p>
  
  <p><code>/priceLists(1)/sections(0)/items(0)</code></p>
  
  <p>to remove the element I tried to use json.prune and it doesn't work, I get this error: error.expected.jsobject</p>
  
  <p>Would would be the best way to do that?</p>
