Prototypes — overview

Opt-in extensions for String, Number, Date, and Array.

typescript

import '@koalarx/utils/prototypes';
// or granular: prototypes/string | number | date | array

Global side-effect. Ideal in Nest main. Avoid on the frontend (bundle).

typescript

'a,,b'.split(',').clearEmptyValues();
(1000).maskCoin();
new Date('2023-10-01').format('dd/MM/yyyy');
