The getInt16() method of DataView instances reads 2 bytes starting at the specified byte offset of this DataView and interprets them as a 16-bit signed integer. There is no alignment constraint; multi-byte values may be fetched from any offset within bounds.

The setBigUint64() method of DataView instances takes a BigInt and stores it as a 64-bit unsigned integer in the 8 bytes starting at the specified byte offset of this DataView. There is no alignment constraint; multi-byte values may be stored at any offset within bounds.

The slice() method of SharedArrayBuffer instances returns a new SharedArrayBuffer whose contents are a copy of this SharedArrayBuffer's bytes from start, inclusive, up to end, exclusive. If either start or end is negative, it refers to an index from the end of the array, as opposed to from the beginning.

The since() method of Temporal.ZonedDateTime instances returns a new Temporal.Duration object representing the duration from another date-time (in a form convertible by Temporal.ZonedDateTime.from()) to this date-time. The duration is positive if the other date-time is before this date-time, and negative if after.

The daysInMonth accessor property of Temporal.PlainDate instances returns a positive integer representing the number of days in the month of this date. It is calendar-dependent.

The eraYear accessor property of Temporal.ZonedDateTime instances returns a non-negative integer representing the year of this date within the era, or undefined if the calendar does not use eras (e.g., ISO 8601). The year index usually starts from 1 (more common) or 0, and years in an era can decrease with time (e.g., Gregorian BCE). era and eraYear together uniquely identify a year in a calendar, in the same way that year does. It is calendar-dependent.

The millisecond accessor property of Temporal.PlainTime instances returns a integer from 0 to 999 representing the millisecond (10-3 second) component of this time.

The weekOfYear accessor property of Temporal.PlainDate instances returns a positive integer representing the 1-based week index in the yearOfWeek of this date, or undefined if the calendar does not have a well-defined week system. The first week of the year is 1. It is calendar-dependent.

The toPlainTime() method of Temporal.PlainDateTime instances returns a new Temporal.PlainTime object representing the time part (hour, minute, second, and subsecond components) of this date-time.

The setInt8() method of DataView instances takes a number and stores it as an 8-bit signed integer in the byte at the specified byte offset of this DataView.
