Once you have installed the library, you can import the eachMonthOfInterval function from the library using the following import statement:

2 lines

Now, you can use the eachMonthOfInterval function to get an array of all the months within the specified interval. The function takes an interval object as an argument, which can be created using the Interval class from the date-fns library. Here is an example usage:

index.ts
import { Interval, eachMonthOfInterval } from 'date-fns';

const interval = new Interval(new Date('2022-01-01'), new Date('2023-12-31'));

const months = eachMonthOfInterval(interval);

console.log(months);
// Output: [Sun Jan 01 2022 00:00:00 GMT+0800 (Malaysia Time), Wed Feb 01 2022 00:00:00 GMT+0800 (Malaysia Time), Wed Mar 01 2022 00:00:00 GMT+0800 (Malaysia Time), Sat Apr 01 2022 00:00:00 GMT+0800 (Malaysia Time), Mon May 01 2022 00:00:00 GMT+0800 (Malaysia Time), Thu Jun 01 2022 00:00:00 GMT+0800 (Malaysia Time), Sat Jul 01 2022 00:00:00 GMT+0800 (Malaysia Time), Tue Aug 01 2022 00:00:00 GMT+0800 (Malaysia Time), Fri Sep 01 2022 00:00:00 GMT+0800 (Malaysia Time), Sun Oct 01 2022 00:00:00 GMT+0800 (Malaysia Time), Wed Nov 01 2022 00:00:00 GMT+0800 (Malaysia Time), Fri Dec 01 2022 00:00:00 GMT+0800 (Malaysia Time), Mon Jan 01 2023 00:00:00 GMT+0800 (Malaysia Time), Thu Feb 01 2023 00:00:00 GMT+0800 (Malaysia Time), Thu Mar 01 2023 00:00:00 GMT+0800 (Malaysia Time), Sun Apr 01 2023 00:00:00 GMT+0800 (Malaysia Time), Tue May 01 2023 00:00:00 GMT+0800 (Malaysia Time), Fri Jun 01 2023 00:00:00 GMT+0800 (Malaysia Time), Sun Jul 01 2023 00:00:00 GMT+0800 (Malaysia Time), Wed Aug 01 2023 00:00:00 GMT+0800 (Malaysia Time), Sat Sep 01 2023 00:00:00 GMT+0800 (Malaysia Time), Mon Oct 01 2023 00:00:00 GMT+0800 (Malaysia Time), Thu Nov 01 2023 00:00:00 GMT+0800 (Malaysia Time), Sat Dec 01 2023 00:00:00 GMT+0800 (Malaysia Time)]

In the example above, we created an interval object that represents the time period from January 1, 2022, to December 31, 2023. We then passed this interval object to the eachMonthOfInterval function, which returned an array of all the months within this time period.

I hope this helps!
