Once you have installed the library, you can use the endOfISOWeekYear function by calling it and passing the date as an argument. The function returns a new Date object representing the end of the ISO week year for the given date.

Here's an example:

const { endOfISOWeekYear } = require('date-fns');

const date = new Date('2022-01-01');
const endOfWeekYear = endOfISOWeekYear(date);

console.log(endOfWeekYear); // Output: 2023-01-01T00:00:00.000Z

In this example, we first import the endOfISOWeekYear function from the date-fns library using destructuring assignment. We then create a new Date object representing January 1st, 2022, and pass it as an argument to the endOfISOWeekYear function. Finally, we log the result to the console, which should be a new Date object representing the end of the ISO week year for January 1st, 2022, i.e., January 1st, 2023.
