    return new Intl.NumberFormat('en-US', {
        style: 'currency',
        currency: currency,
    }).format(amount);
};

Currency Symbol Mapping

const getCurrencySymbol = (currency: string): string => {
    const symbols = {
        'USD': '$', 'EUR': '€', 'GBP': '£', 'PKR': '₨',
        'INR': '₹', 'JPY': '¥', 'AED': 'د.إ'
        // ... more currencies
    };
