Temporal.Instant.prototype.equals()
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
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
equals(other)
Parameters
other
-
A string or a
Temporal.Instant
instance representing the other instant to compare. It is converted to aTemporal.Instant
object using the same algorithm asTemporal.Instant.from()
.
Return value
true
if this instant is equal to other
by nanoseconds, false
otherwise.
Examples
Using equals()
const instant1 = Temporal.Instant.from("2021-08-01T12:34:56Z");
const instant2 = Temporal.Instant.fromEpochMilliseconds(1627821296000);
console.log(instant1.equals(instant2)); // true
