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

To use the startOfYear function from date-fns in JavaScript, you first need to install the package. You can do this using npm or yarn by running the following command in your terminal:

index.tsx
npm install date-fns
21 chars
2 lines

or

index.tsx
yarn add date-fns
18 chars
2 lines

Once you have installed the package, you can then import the startOfYear function into your JavaScript code and use it as follows:

import { startOfYear } from 'date-fns';

const date = new Date();
const startOfYearDate = startOfYear(date);

console.log(startOfYearDate);
// Output: Sun Jan 01 2023 00:00:00 GMT+0000 (Coordinated Universal Time)

In the above example, we are importing the startOfYear function from date-fns. We are then creating a new date object and passing it to the startOfYear function. This function returns the start of the year for the given date. We then log the result to the console.

Note that startOfYear returns a new date object, so it does not modify the original date object.
