//        "eula_create_date": 1649108951523
//      }
//    ]
//  }

//  The destination is the empty "users" array, the source is the populated "users" array in jsonB.
oJsonUsersDest := CreateObject("Chilkat.JsonArray")

//  Copy the array items from source to dest
oJsonUsersDest:AppendArrayItems(oJsonUsersSrc)

? oJsonA:Emit()

//  The end result is this:

//    "ciphertext": "encryptedData",
