how to use the isafter function from the date-fns library in typescript

To use the isAfter function from the date-fns library in TypeScript, make sure to install both date-fns and @types/date-fns. Then you can import the function and use it in your code:

index.ts
import { isAfter } from 'date-fns';

const date1 = new Date('2021-01-01');
const date2 = new Date('2021-07-01');

if (isAfter(date2, date1)) {
  console.log('date2 is after date1');
}

Note that the isAfter function takes two arguments of type Date and returns a boolean value indicating whether the first date is after the second date. Also, importing isAfter from date-fns makes use of the TypeScript type definitions for date-fns, which ensure better type safety when working with dates in your code.
