how to use the setyear function from the date-fns library in typescript

To use the setYear() function from the date-fns library in TypeScript, you need to first install the date-fns package using your package manager of choice. You can do this by running npm install date-fns if you're using npm.

After installing the date-fns package, you can import the setYear() function from the package:

index.ts
import { setYear } from 'date-fns';

The setYear() function takes two arguments: a date object and a year value. It returns a new Date object with the year set to the specified value.

Here's an example of how to use the setYear() function:

index.ts
const myDate = new Date('2021-01-01');
const newDate = setYear(myDate, 2022);

console.log(newDate.getFullYear()); // Output: 2022

In this example, we create a new Date object with the date set to January 1st, 2021. We then call the setYear() function with this Date object and a new year value of 2022. The function returns a new Date object with the year set to 2022. We then log the new year using the .getFullYear() method on the Date object, which outputs 2022.
