How to get a single object in an array to a JSON model

I have a JSON model /details with 4 objects. I want the object based on the key :month.

   Object
   oData
   details:
   Array[4]
   0:Object
   1:Object
   2:Object
   3:Object
    editable:false
    key:"date"
    removeable:false
    value:"Day: TRUE, Night:False"
   4:Object
    editable:false
    key:"month"
    removeable:false

You cannot query the object directly. You have to loop and search like so:

var viewModel = that.getView().getModel();
var viewModelData = viewModel.getProperty("/details");
var month = getObjectByKey(viewModelData, "month");

function getObjectByKey(a, key){
  for(var i = 0; i < a.length; i++){
  if (a[i].key === key){
    return a[i];
  }
  return null;
}
