如何比较Luxon中的持续时间或间隔？

const DateTime = luxon.DateTime;

const start = DateTime.fromISO('2022-01-01T00:00:00');
const end = DateTime.fromISO('2022-01-01T12:00:00');

const diff = end.diff(start);

console.log(diff.values); // { milliseconds: 43200000, seconds: 43200, minutes: 720, hours: 12, days: 0, months: 0, years: 0 }

const Duration = luxon.Duration;
const Interval = luxon.Interval;

const duration = Duration.fromObject({ hours: 12 });
const interval = Interval.fromDateTimes(start, end);

console.log(Duration.isDuration(duration)); // true
console.log(Duration.isDuration(interval)); // false
console.log(Interval.isInterval(duration)); // false
console.log(Interval.isInterval(interval)); // true

const duration1 = Duration.fromObject({ hours: 12 });
const duration2 = Duration.fromObject({ hours: 24 });

console.log(duration1 < duration2); // true
console.log(duration1 === duration2); // false
console.log(duration1 > duration2); // false
