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

eachQuarterOfInterval is a date-fns function that returns an array with the quarters within a given interval. Here's how you can use it in JavaScript:

First, you would need to install the date-fns library using npm:

npm install date-fns
21 chars
2 lines

Then, you can import the eachQuarterOfInterval function and use it like this:

index.tsx
import { eachQuarterOfInterval } from 'date-fns'

const start = new Date(2021, 0, 1) // January 1st, 2021
const end = new Date(2021, 11, 31) // December 31st, 2021
const quarters = eachQuarterOfInterval({ start, end })

console.log(quarters)
// Output: [ Date(2021, 0, 1), Date(2021, 3, 1), Date(2021, 6, 1), Date(2021, 9, 1) ]

9 lines

In this example, we're creating a date range between January 1st, 2021 and December 31st, 2021 using the Date constructor. Then, we pass this range as an object with start and end properties to the eachQuarterOfInterval function to get an array with the quarterly dates within the range. Finally, we're logging the resulting array to the console.

Hope this helps!
