Expected pipeline result

Once executed, you'll see that the same number of documents appear in the new orders_typed collection as the source collection had, with the same field structure and fields names, but now using the strongly-typed boolean, date, integer, and decimal values where appropriate, as shown in the following result:

[ { _id: ObjectId('6064381b7aa89666258201fd'), customer_id: '[email protected]', further_info: { item_qty: 3, reported: false }, order_date: ISODate('2020-05-30T08:35:52.000Z'), value: NumberDecimal('231.43') }, { _id: ObjectId('6064381b7aa89666258201fe'), customer_id: '[email protected]', further_info: { item_qty: 2 }, order_date: ISODate('2020-01-01T08:25:37.000Z'), value: NumberDecimal('63.13') }, { _id: ObjectId('6064381b7aa89666258201ff'), customer_id: '[email protected]',\ further_info: { item_qty: 1, reported: true }, order_date: ISODate('2019-05-28T19:13:32.000Z'), value: NumberDecimal('2.01') } ]
