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

To use the setYear function from the date-fns library in JavaScript, you first need to install the package using npm (Node Package Manager). In your terminal, navigate to your project directory and run the following command:

npm install date-fns --save

Once you've installed the package, you can import the setYear function into your JavaScript code like this:

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

2 lines

Alternatively, if you're using ES6 modules, you can import the function like this:

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

2 lines

Now that you have imported the setYear function, you can use it to set the year of a JavaScript Date object. The function takes two arguments: the date object you want to modify, and the year you want to set it to. Here's an example:

index.tsx
const myDate = new Date('2021-03-23');
console.log(myDate); // Output: Tue Mar 23 2021 00:00:00 GMT-0700 (Pacific Daylight Time)

const modifiedDate = setYear(myDate, 2022);
console.log(modifiedDate); // Output: Sat Mar 23 2022 00:00:00 GMT-0700 (Pacific Daylight Time)

In this example, we create a new Date object set to March 23, 2021. We then pass this object and the integer 2022 to the setYear function, which returns a new Date object with the year set to 2022. We store this new object in the modifiedDate variable and print it to the console.

That's how you can use the setYear function from the date-fns library in JavaScript!
