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

The isSameYear function from date-fns allows you to compare two dates to check if they are in the same year. Here is an example of how to use it:

index.tsx
import { isSameYear } from 'date-fns';

const date1 = new Date('2022-01-01');
const date2 = new Date('2021-12-31');

console.log(isSameYear(date1, date2)); // Output: false

const date3 = new Date('2022-01-01');
const date4 = new Date('2022-12-31');

console.log(isSameYear(date3, date4)); // Output: true

In the example above, we first import the isSameYear function from the date-fns library. We then create four Date objects, two of which are in the same year and two that aren't. We then call the isSameYear function with each of these date pairs as arguments, and true is returned for the dates in the same year and false is returned for the ones that aren't.

Note that the isSameYear function only compares the year component of the dates, ignoring any other components like month, day, or time.
