The reduce() method of TypedArray instances executes a user-supplied "reducer" callback function on each element of the typed array, in order, passing in the return value from the calculation on the preceding element. The final result of running the reducer across all elements of the typed array is a single value. This method has the same algorithm as Array.prototype.reduce().

The equals() method of Temporal.Instant instances returns true if this instant is equivalent in value to another instant (in a form convertible by Temporal.Instant.from()), and false otherwise. They are compared by their epochNanoseconds. It is equivalent to Temporal.Instant.compare(this, other) === 0.

The epochNanoseconds accessor property of Temporal.Instant instances returns a BigInt representing the number of nanoseconds elapsed since the Unix epoch (midnight at the beginning of January 1, 1970, UTC) to this instant.

The Temporal.PlainTime.compare() static method returns a number (-1, 0, or 1) indicating whether the first time comes before, is the same as, or comes after the second time. It is equivalent to comparing the hour, minute, second, millisecond, microsecond, and nanosecond fields one by one.

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 Temporal.PlainTime() constructor creates Temporal.PlainTime objects.

The subtract() method of Temporal.PlainYearMonth instances returns a new Temporal.PlainYearMonth object representing this year-month moved backward by a given duration (in a form convertible by Temporal.Duration.from()).
