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

The lastDayOfQuarter function from the date-fns library can be used to get the last day of a quarter. Here is an example:

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

const date = new Date();
const lastDay = lastDayOfQuarter(date);

console.log(lastDay); // Output: 2022-03-31T04:59:59.999Z

In this example, we are requiring the lastDayOfQuarter function from the date-fns library. We then create a new instance of the Date object and pass it to the lastDayOfQuarter function. This returns the last day of the quarter for the specified date.

The lastDayOfQuarter function also accepts an optional options object as its second parameter, which allows you to specify the start day of the week and the locale to use.
