Quick example

import { formatDate, hexToRGB, mulberry32 } from '@basmilius/utils';
import { DateTime } from 'luxon';

formatDate(DateTime.now()); // localized date string
hexToRGB('#0070f3');         // [0, 112, 243]
const random = mulberry32(42); // seeded PRNG
random.next();                  // deterministic 0..1 value
