After finding out the elements which are in list4 but not in list3, we are using that list to match with the elements in list4, so we get the complete structure of list4 only for the different items. To start, specify the path to the parent object or collection and the property subpath within the parent where the array is located. Weve effectively grouped all the data into their own orders.
