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

To use the nextSaturday function from the date-fns library in JavaScript, you first need to install the library via npm or add it to your project manually.

Assuming you have installed date-fns, you can then import the nextSaturday function and use it in your code like this:

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

const today = new Date();
const nextSat = nextSaturday(today);

console.log(nextSat); // Output: 2021-10-09T04:00:00.000Z

In the above code, we first imported the nextSaturday function from the date-fns library. We then created a new Date object, representing today's date. We then called the nextSaturday function with this date object as its argument, which returns the next Saturday after the given date.

The resulting nextSat variable holds a Date object representing the next Saturday after today's date. Finally, we printed this value to the console using console.log.

Note that the nextSaturday function returns a Date object representing the start of the day (midnight) in UTC time. You may need to adjust this value to match your local time zone.
