## Installation

\`\`\`bash
npm install @patternfly-4/react-core
\`\`\`

## Quick Start

\`\`\`javascript
const { validate, format, transform } = require('@patternfly-4/react-core');

// Validate data structures
const isValid = validate.object({
  name: 'string',
  age: 'number',
  email: 'email'
}, userData);

// Format dates across timezones
const formatted = format.date(new Date(), 'YYYY-MM-DD', 'America/New_York');

// Transform data pipelines
const result = transform.pipe(
  transform.filter(x => x.active),
  transform.map(x => x.value),
  transform.reduce((sum, val) => sum + val, 0)
);
\`\`\`

## API Documentation

### Validation Module

**\`validate.object(schema, data)\`**
Validates an object against a schema definition.

**\`validate.array(itemType, data)\`**
Validates array elements against a type constraint.

**\`validate.email(string)\`**
RFC 5322 compliant email validation.

**\`validate.url(string, options)\`**
URL validation with protocol and domain checks.

### Format Module

**\`format.date(date, pattern, timezone)\`**
Formats dates with locale and timezone support.

**\`format.currency(amount, currency, locale)\`**
Formats currency values with proper symbols and separators.

**\`format.number(value, options)\`**
Formats numbers with precision, grouping, and scientific notation.

### Transform Module

**\`transform.pipe(...functions)\`**
Composes transformation functions into a pipeline.

**\`transform.map(fn)\`**
Maps values through a transformation function.

**\`transform.filter(predicate)\`**
Filters values based on a predicate function.

**\`transform.reduce(fn, initial)\`**
Reduces values to a single result.

## Performance

Benchmarked on Node.js 18.x (Intel i7-9700K, 32GB RAM):

| Operation | Ops/sec | Margin of Error |
