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

To use the toLocaleString function from the date-fns library in TypeScript, you can import it from the package as follows:

index.ts
import { format } from 'date-fns';
import { enGB } from 'date-fns/locale';
75 chars
3 lines

Then, to obtain a formatted date using toLocaleString, you can define a Date object and pass it to the format function with the desired format string and locale:

index.ts
const date = new Date();
const formattedDate = format(date, 'eeee, LLLL do yyyy', { locale: enGB });
101 chars
3 lines

In this example, formattedDate will contain a string representing the current date in the format "Monday, June 7th 2021" using the enGB locale.

You can customize the format string to meet your needs, and you can also use other locales by importing them from the date-fns/locale package.
