To use the set function from date-fns, you need to first install the date-fns package. You can use npm to install it with the following command:

npm install date-fns

2 lines

Once installed, you can import the set function and use it to set a specific date value. The set function takes three arguments: the date object to modify, the property to modify (such as 'year', 'month', 'date', etc.), and the new value to set.

Here's an example of how to use the set function to change the year of a date:

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

const date = new Date('2021-01-01');
const newYear = 2022;

const updatedDate = set(date, 'year', newYear);

console.log(updatedDate); // Output: Fri Dec 31 2021 19:00:00 GMT-0500 (Eastern Standard Time)

In this example, we create a new Date object for January 1st 2021. We then call the set function to change the year to 2022. The updatedDate variable now holds a new Date object representing December 31st 2021 with the updated year value.

You can use the same function to set other date properties, such as the month or date. Refer to the set function documentation for more information on supported properties.
