The toJSON() method of Temporal.PlainDate instances returns a string representing this date in the same RFC 9557 format as calling toString(). It is intended to be implicitly called by JSON.stringify().

The monthCode accessor property of Temporal.PlainYearMonth instances returns a calendar-specific string representing the month of this year-month. It is calendar-dependent.

The map() method of Iterator instances returns a new iterator helper object that yields elements of the iterator, each transformed by a mapping function.

The throw() method of Generator instances acts as if a throw statement is inserted in the generator's body at the current suspended position, which informs the generator of an error condition and allows it to handle the error, or perform cleanup and close itself.

The month accessor property of Temporal.PlainDateTime instances returns a positive integer representing the 1-based month index in the year of this date. The first month of this year is 1, and the last month is the monthsInYear. It is calendar-dependent.

The startOfDay() method of Temporal.ZonedDateTime instances returns a Temporal.ZonedDateTime object representing the first instant of this date in the time zone. It usually has a time of 00:00:00, but may be different if the midnight doesn't exist due to offset changes, in which case the first time that exists is returned.
