To use the issamequarter function from date-fns, you'll need to first install the date-fns package by running the following npm command:

2 lines

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

index.tsx
import { isSameQuarter } from 'date-fns'
41 chars
2 lines

Then, you can use the function to compare two dates and see if they are in the same quarter:

index.tsx
const date1 = new Date('2021-01-01')
const date2 = new Date('2021-05-01')

const isSameQuarterResult = isSameQuarter(date1, date2)

console.log(isSameQuarterResult) // Output: true

In this example, we're comparing two dates (date1 and date2), and using the isSameQuarter function to determine if they are in the same quarter. The function returns true if both dates are in the same quarter, and false otherwise.
