The forEach() method of Set instances executes a provided function once for each value in this set, in insertion order.

The [Symbol.iterator]() method of Set instances implements the iterable protocol and allows Set objects to be consumed by most syntaxes expecting iterables, such as the spread syntax and for...of loops. It returns a set iterator object that yields the values of the set in insertion order.

The nanosecond accessor property of Temporal.PlainDateTime instances returns a integer from 0 to 999 representing the nanosecond (10-9 second) component of this time.

The getTimeZoneTransition() method of Temporal.ZonedDateTime instances returns a Temporal.ZonedDateTime object representing the closest instant after or before this instant at which the time zone's UTC offset changes (the returned instant is the first instant after the change), or null if there is no such transition. This is useful for finding out the offset rules of a time zone, such as its daylight saving time pattern.

The handler.isExtensible() method is a trap for the [[IsExtensible]] object internal method, which is used by operations such as Object.isExtensible().

The handler.apply() method is a trap for the [[Call]] object internal method, which is used by operations such as function calls.

The unregister() method of FinalizationRegistry instances unregisters a target value from this FinalizationRegistry.

The register() method of FinalizationRegistry instances registers an value with this FinalizationRegistry so that if the value is garbage-collected, the registry's callback may get called.
