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

To use the eachDayOfInterval function from the date-fns library in TypeScript, first you need to install the date-fns package using a package manager like npm:

npm install date-fns

Then, you can import the eachDayOfInterval function from the library and use it in your TypeScript code like this:

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

const startDate = new Date('2022-01-01');
const endDate = new Date('2022-01-10');

const interval = { start: startDate, end: endDate };
const result = eachDayOfInterval(interval);

console.log(result); // [ Sat Jan 01 2022 00:00:00 GMT+0100 (Central European Standard Time), Sun Jan 02 2022 00:00:00 GMT+0100 (Central European Standard Time), Mon Jan 03 2022 00:00:00 GMT+0100 (Central European Standard Time), Tue Jan 04 2022 00:00:00 GMT+0100 (Central European Standard Time), Wed Jan 05 2022 00:00:00 GMT+0100 (Central European Standard Time), Thu Jan 06 2022 00:00:00 GMT+0100 (Central European Standard Time), Fri Jan 07 2022 00:00:00 GMT+0100 (Central European Standard Time), Sat Jan 08 2022 00:00:00 GMT+0100 (Central European Standard Time), Sun Jan 09 2022 00:00:00 GMT+0100 (Central European Standard Time), Mon Jan 10 2022 00:00:00 GMT+0100 (Central European Standard Time) ]

In this example, we first create a start date and an end date for our interval. Then, we create an object that represents our interval using these dates. We pass this interval object to the eachDayOfInterval function, which returns an array of all the dates in the interval. Finally, we log the result to the console.

You can customize the behavior of the eachDayOfInterval function further by passing an options object as a second argument. For more information on the available options, see the eachDayOfInterval documentation in the date-fns library.
