title: Gatling convert Json array to Map
body: <p>I have json such as ["123","123a","12c3","1f23","e123","r123"]
  as response from rest server.</p>
  
  <p>I want to parse this json as Collection and iterate over it and make exec request over each element in it
  such as :</p>
  
  <p>SERVER + "/get?param=${el}"
  where el will be 123,123a,12c3,1f23,e123 and r123</p>
  
  <p>My question is how can I do it.</p>
