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

The compareDesc function from date-fns is used to compare two dates and determine if they are in descending order. Here's an example of how to use it:

index.tsx
import { compareDesc } from 'date-fns';

const date1 = new Date('2022-03-14');
const date2 = new Date('2022-03-15');

const result = compareDesc(date1, date2);

console.log(result); // Output: 1, which means `date1` is before `date2`
234 chars
9 lines

In the example above, we import the compareDesc function from date-fns. We then create two Date objects representing date1 and date2. Finally, we call compareDesc with date1 and date2 as arguments, which returns 1, indicating that date1 is before date2.

It's important to note that compareDesc expects Date objects as arguments. If you have date strings or timestamps, you'll need to convert them to Date objects first.
