Utility Functions

timeSlotDifference

Included in the package is a utility function timeSlotDifference to easily get an array of available time slots less an array of unavailable time slots. In other words, if you have an array of time slots that are available and a separate array of timeslots that are unavailable, this utility function will start with the available time slots and remove any time from an intersecting unavailable time slot.

import { timeSlotDifference } from 'react-schedule-meeting';

const availableTimeSlots = [
  {
    startTime: new Date('2023-01-01T09:00:00.000Z'),
    endTime: new Date('2023-01-01T12:00:00.000Z'),
  },
  {
    startTime: new Date('2023-01-01T13:30:00.000Z'),
    endTime: new Date('2023-01-01T17:00:00.000Z'),
  },
  {
    startTime: new Date('2023-01-01T18:00:00.000Z'),
    endTime: new Date('2023-01-01T19:30:00.000Z'),
