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

The add() method of Temporal.Instant instances returns a new Temporal.Instant object representing this instant moved forward by a given duration (in a form convertible by Temporal.Duration.from()).

The epochMilliseconds accessor property of Temporal.Instant instances returns an integer representing the number of milliseconds elapsed since the Unix epoch (midnight at the beginning of January 1, 1970, UTC) to this instant. It is equivalent to dividing epochNanoseconds by 1e6 and flooring the result.

The Temporal.PlainDate.compare() static method returns a number (-1, 0, or 1) indicating whether the first date comes before, is the same as, or comes after the second date. Equivalent to comparing the year, month, and day fields of the underlying ISO 8601 dates.

The month accessor property of Temporal.PlainDate 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 DataView() constructor creates DataView objects.

The BigInt64Array() constructor creates BigInt64Array objects. The contents are initialized to 0n unless initialization data is explicitly provided.

The Float64Array() constructor creates Float64Array objects. The contents are initialized to 0 unless initialization data is explicitly provided.
