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.

Syntax

js
equals(other)

Parameters

other

A string or a Temporal.Instant instance representing the other instant to compare. It is converted to a Temporal.Instant object using the same algorithm as Temporal.Instant.from().

Return value

true if this instant is equal to other by nanoseconds, false otherwise.

Examples

Using equals()

js
const instant1 = Temporal.Instant.from("2021-08-01T12:34:56Z");
const instant2 = Temporal.Instant.fromEpochMilliseconds(1627821296000);
console.log(instant1.equals(instant2)); // true
