Then in your TypeScript file, you can import addMonths and use it as follows:

index.ts
import addMonths from 'date-fns/addMonths';

const originalDate = new Date('2022-05-25');
const numberOfMonthsToAdd = 3;
const newDate = addMonths(originalDate, numberOfMonthsToAdd);

console.log(newDate);
// Output: Sat Aug 25 2022 00:00:00 GMT-0500 (Central Daylight Time)

In the example above, we imported the addMonths function from date-fns/addMonths. We then defined a Date object representing our original date, and the number of months we want to add to that date. Finally, we passed these two values to addMonths to get a new Date object representing the new date with the desired number of months added.
