3. Call the intervalToDuration function and pass in an interval object as an argument. The interval object should have a start and end property that represent the start and end dates of the interval. For example:

const interval = {
  start: new Date(2022, 0, 1, 12, 0, 0),
  end: new Date(2022, 0, 1, 13, 30, 0),
};

const duration = intervalToDuration(interval);
console.log(duration); // { hours: 1, minutes: 30 }

The duration variable will now contain an object that represents the duration of the interval in hours, minutes, seconds, and milliseconds. In this example, the interval was 1 hour and 30 minutes long.
