Question

Using JSON, each document is a list of key-value pairs. How do you enter a order data value like 2009-12-23?

A) OrderDate: new Date()
B) "OrderDate": ISODate("2009-12-23")
C) Order Date: new Date(2009, 12, 23)
D) OrderDate: ISODate(2009, 12, 23)

Answer 1

In JSON, an order date value like 2009-12-23 should be entered as a string, with the correct format resembling option B: "OrderDate": "2009-12-23".

Step-by-step explanation:

The correct way to enter an order date value like 2009-12-23 in JSON is by using a string to represent the date value since JSON does not have a native Date type. Among the options provided, the most appropriate format that resembles how dates are usually represented in JSON is option B: "OrderDate": "2009-12-23". Nevertheless, this representation does not include any explicit mention of time zone or ISODate which may be specific to certain databases like MongoDB. Pure JSON would simply use a string to represent the date.
