Usage

import { array, string, object, validate, math } from 'js-helpers';

// Array utilities
array.chunk([1, 2, 3, 4], 2);           // [[1, 2], [3, 4]]
array.unique([1, 1, 2, 3]);             // [1, 2, 3]
array.groupBy(items, 'type');            // { a: [...], b: [...] }

// String utilities
string.camelCase('hello-world');         // 'helloWorld'
string.kebabCase('helloWorld');          // 'hello-world'
string.slugify('Hello World!');          // 'hello-world'

// Object utilities
object.deepClone({ a: { b: 1 } });     // Deep copy
object.get({ a: { b: 42 } }, 'a.b');   // 42

// Validation
validate.isEmail('test@example.com');    // true
validate.isStrongPassword('P@ss123');    // true

// Math utilities
math.clamp(15, 0, 10);                  // 10
math.average([1, 2, 3, 4]);             // 2.5
