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

Once you have installed date-fns, you can use the subBusinessDays function as shown in the code below:

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

const currentDate = new Date();
const numberOfDaysToSubtract = 3;

const resultDate = subBusinessDays(currentDate, numberOfDaysToSubtract);
console.log(resultDate);

In the example above, we imported the subBusinessDays function from date-fns and used it to subtract 3 business days from the current date. The result is stored in the resultDate variable and printed to the console.

Note that subBusinessDays only subtracts business days and ignores weekends (Saturday and Sunday) by default. If you need to include holidays, you can pass an array of holiday dates as the third argument to subBusinessDays.
