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

To use setDefaultOptions function from date-fns, you need to import it first from the package.

Here's how you can use it:

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

const options = {
  locale: fr,
  weekStartsOn: 1,
  additionalDigits: 2,
};

setDefaultOptions(options);
153 chars
10 lines

The setDefaultOptions function will set the new default options for all functions that use the options object in the date-fns package. This way, you don't have to pass the options object every time you use a date-fns function.

Note that the options object follows the date-fns option specification. For more information, you can check out the date-fns documentation.
