To use the subquarters function from the date-fns library in JavaScript, you first need to install the library in your project using a package manager like npm or yarn.

npm install date-fns

2 lines

Once you have installed the library, you can use the subquarters function to subtract a number of quarters from a date object.

Here's an example:

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

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

// Subtract 2 quarters from the date
const result = subquarters(date, 2);

console.log(result);

In this example, we import the subquarters function from date-fns and create a Date object representing January 1st, 2021. We then subtract 2 quarters from the date using the subquarters function and log the result to the console.

The output of this code will be:

index.tsx
2020-04-01T00:00:00.000Z
25 chars
2 lines

This is because we have subtracted 2 quarters from January 1st, 2021, which takes us back to April 1st, 2020.
