how to use the isafter function from date-fns in javascript

You can use the isAfter function from the date-fns library to check if a date is after another date. Here is an example:

index.tsx
const dateFns = require('date-fns');

const date1 = new Date('2021-01-01');
const date2 = new Date('2022-01-01');

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

In this example, we are creating two Date objects representing January 1st of 2021 and 2022. We are then using isAfter to check if date2 is after date1. Since date2 is January 1st of 2022 and date1 is January 1st of 2021, date2 is indeed after date1.

The isAfter function takes two arguments: dateToCheck and dateToCompare. It returns true if dateToCheck is after dateToCompare, and false otherwise.
