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

To use the subquarters function from the date-fns library in TypeScript, you can follow these steps:

1. Install date-fns using npm or yarn:

   npm install date-fns
   21 chars
   2 lines

   or

   yarn add date-fns
   18 chars
   2 lines

2. Import the subquarters function:

   index.ts
   import { subQuarters } from 'date-fns';
   40 chars
   2 lines

3. Call the subQuarters function with a date and the number of quarters to subtract as arguments:

   index.ts
   const date = new Date();
   const result = subQuarters(date, 2);
   console.log(result); // 2 quarters ago from the current date
   123 chars
   4 lines

Here's a complete code example:

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

const date = new Date();
const result = subQuarters(date, 2);
console.log(result); // 2 quarters ago from the current date
164 chars
6 lines

In this example, we imported the subQuarters function from date-fns, called it with the current date and the number 2 as arguments, and printed the result to the console.
