var data1 = [{
    field1: '111',
    field2: '222',
    field3: '333',
    field4: [{
            field5: '555',
            field6: '666',
            field7: '777'
        },
        {
            field5: '5555',
            field6: '6666',
            field7: '7777'
        }
    ],
    field8: [{
            field9: '999',
            field10: '101010',
            field11: '111111'

            }
        }
        return newItem;
    });
}

console.log(JSON.stringify(transformData(data1)))
