Quick Start

import { businessDaysBetween } from '@toolpouch/sdk/dates';
import { formatJSON } from '@toolpouch/sdk/data';
import { toCamelCase } from '@toolpouch/sdk/text';

// Date calculations
const days = businessDaysBetween('2026-01-01', '2026-12-31');
// { businessDays: 261, calendarDays: 364, weekendDays: 104 }

// JSON formatting
const formatted = formatJSON('{"name":"test","value":42}', 2);

// Text transformation
const camel = toCamelCase('hello world test'); // 'helloWorldTest'
