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

You can use the isBefore function from the date-fns library to check if one date is before another date in JavaScript. Here's an example of how to use it:

index.tsx
const { isBefore } = require('date-fns');

const date1 = new Date('2020-01-01');
const date2 = new Date('2020-02-01');

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

In this example, the isBefore function is imported from the date-fns library using destructuring. Two date objects are then created using the Date constructor. The isBefore function is then used to compare the two dates. If date1 is before date2, the first string will be logged to the console. Otherwise, the second string will be logged instead.
