// Define the 'toCurrency' function.
const toCurrency = (n, curr, languageFormat = undefined) =>
  Intl.NumberFormat(languageFormat, { style: 'currency', currency: curr }).format(n);

// Test the 'toCurrency' function with sample inputs.
console.log(toCurrency(123456.789, 'EUR')); // Output: "€123,456.79"
console.log(toCurrency(123456.789, 'USD', 'en-us')); // Output: "$123,456.79"
console.log(toCurrency(123456.789, 'USD', 'fa')); // Output: "۱۲۳٬۴۵۶٫۷۹ US$"
console.log(toCurrency(322342436423.2435, 'JPY')); // Output: "¥322,342,436,423"
