The equals() method of Temporal.PlainTime instances returns true if this time is equivalent in value to another time (in a form convertible by Temporal.PlainTime.from()), and false otherwise. They are compared by their time values. It is equivalent to Temporal.PlainTime.compare(this, other) === 0.
equals(other)otherA string, an object, or a Temporal.PlainTime instance representing the other time to compare. It is converted to a Temporal.PlainTime object using the same algorithm as Temporal.PlainTime.from().
true if this time is equal to other both in their time value and their calendar, false otherwise.
const time1 = Temporal.PlainTime.from("12:34:56");
const time2 = Temporal.PlainTime.from({ hour: 12, minute: 34, second: 56 });
console.log(time1.equals(time2)); // true
const time3 = Temporal.PlainTime.from("00:34:56");
console.log(time1.equals(time3)); // false
