Temporal.PlainDate.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.PlainDate instances returns true if this date is equivalent in value to another date (in a form convertible by Temporal.PlainDate.from()), and false otherwise. They are compared both by their date values and their calendars, so two dates from different calendars may be considered equal by Temporal.PlainDate.compare() but not by equals().
Syntax
equals(other)
Parameters
other-
A string, an object, or a
Temporal.PlainDateinstance representing the other date to compare. It is converted to aTemporal.PlainDateobject using the same algorithm asTemporal.PlainDate.from().
Return value
true if this date is equal to other both in their date value and their calendar, false otherwise.
Examples
Using equals()
const date1 = Temporal.PlainDate.from("2021-08-01");
const date2 = Temporal.PlainDate.from({ year: 2021, month: 8, day: 1 });
console.log(date1.equals(date2)); // true
const date3 = Temporal.PlainDate.from("2021-08-01[u-ca=japanese]");
console.log(date1.equals(date3)); // false
const date4 = Temporal.PlainDate.from("2021-08-02");
console.log(date1.equals(date4)); // false
