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

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

index.tsx
npm install date-fns

2 lines

Once you have installed the package, you can import the add function into your JavaScript file like this:

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

Alternatively, if you are using ES6 modules, you can import it like this:

import { add } from 'date-fns';
32 chars
2 lines

Once you have imported the function, you can use it to add a specified amount of time to a given date. The function takes three parameters: the date you want to add time to, an object specifying the amount of time to add, and optional additional options.

Here's an example of how to use the add function to add 5 days to a date:

const myDate = new Date('2022-01-01')
const newDate = add(myDate, { days: 5 })
console.log(newDate) // Output: Thu Jan 06 2022 00:00:00 GMT+0530 (India Standard Time)

In the code above, we create a new date object for January 1st, 2022. We then pass this date, along with an object specifying that we want to add 5 days, to the add function. The function returns a new date object with 5 days added. We log this new date to the console to verify that it has been modified correctly.

This is just one example of how you can use the add function from date-fns. You can also use it to add other units of time, such as minutes, hours, and months. Check out the official documentation for more information and examples: https://date-fns.org/v2.23.0/docs/add.
