    // Let's say we want to insert jsonB into jsonA to get this:

    // {
    //   "ciphertext": "encryptedData",
    //   "status": 200,
    //   "error": "errorMsg",
    //   "users": [

    //       "eula_create_date": 1649108922482
    //     },
    //     {
    //       "role": "Support",
    //       "sub_roles": [
    //         "Tech",
    //         "Service"
    //       ],
    //       "viewable_for_sharing": true,
    //       "eula_create_date": 1649108951523
    //     }
    //   ]
    // }

    // First add an empty array at the desired location (-1 means append to end).
    jsonA.AddArrayAt(-1,"users");

    // The destination is the empty "users" array, the source is the populated "users" array in jsonB.
    // jsonUsersDest: JsonArray
    var jsonUsersDest = jsonA.ArrayOf("users");
    // jsonUsersSrc: JsonArray
    var jsonUsersSrc = jsonB.ArrayOf("users");
    // Copy the array items from source to dest
    jsonUsersDest.AppendArrayItems(jsonUsersSrc);

    console.log(jsonA.Emit());

    // The end result is this:

    // {
    //   "ciphertext": "encryptedData",
    //   "status": 200,
    //   "error": "errorMsg",
    //   "users": [
