Temporal.PlainDateTime.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.PlainDateTime instances returns true if this date-time is equivalent in value to another date-time (in a form convertible by Temporal.PlainDateTime.from()), and false otherwise. They are compared both by their date and time values and their calendars, so two date-times from different calendars may be considered equal by Temporal.PlainDateTime.compare() but not by equals().
Syntax
equals(other)
Parameters
other-
A string, an object, or a
Temporal.PlainDateTimeinstance representing the other date-time to compare. It is converted to aTemporal.PlainDateTimeobject using the same algorithm asTemporal.PlainDateTime.from().
Return value
true if this date-time is equal to other both in their date/time value and their calendar, false otherwise.
Examples
Using equals()
const dt1 = Temporal.PlainDateTime.from("2021-08-01");
const dt2 = Temporal.PlainDateTime.from({ year: 2021, month: 8, day: 1 });
console.log(dt1.equals(dt2)); // true
const dt3 = Temporal.PlainDateTime.from("2021-08-01[u-ca=japanese]");
console.log(dt1.equals(dt3)); // false
const dt4 = Temporal.PlainDateTime.from("2021-08-01T01:00:00");
console.log(dt1.equals(dt4)); // false
