const uuid = generateUUID();
console.log(uuid); // "12345678-1234-4123-8123-123456789012"

// Generate multiple UUIDs
const uuids = generateUUIDs(5);
console.log(uuids); // ["uuid1", "uuid2", "uuid3", "uuid4", "uuid5"]

// Validate a UUID
const isValid = isValidUUID("12345678-1234-4123-8123-123456789012");
console.log(isValid); // true

Advanced Usage

import {
  generatePrefixedUUID,
  generateUUIDCompact
} from 'uuid-generator-krishnarao';

// Generate UUID with prefix
const prefixedUUID = generatePrefixedUUID("user");
console.log(prefixedUUID); // "user-12345678-1234-4123-8123-123456789012"

// Generate compact UUID (without hyphens)
const compactUUID = generateUUIDCompact();
