After that, you can import the function into your code and use it like this:

index.tsx
const { endOfWeek } = require('date-fns');

const date = new Date(); // or any other date
const endOfWeekDate = endOfWeek(date);

console.log(endOfWeekDate); // output: a Date object representing the end of the week

The endOfWeek function takes a Date object as its argument and returns a new Date object representing the end of the week for the given date. By default, the week starts on Sunday and ends on Saturday, but you can customize this behavior by passing an options object as a second argument to the function.

For example, to make the week start on Monday instead of Sunday, you can do this:

index.tsx
const { endOfWeek } = require('date-fns');

const date = new Date(); // or any other date
const endOfWeekDate = endOfWeek(date, { weekStartsOn: 1 }); // 1 = Monday

console.log(endOfWeekDate); // output: a Date object representing the end of the week (Monday - Sunday)
