JavaScript の Intl オブジェクトの探索

Did you know that JavaScript has a built-in object called Intl that makes your applications truly global?

The Intl (Internationalization) object provides powerful tools to format dates, numbers, and currencies according to the user's locale, all without any additional libraries.

It’s perfect for creating applications that support multiple languages and regions seamlessly!

Example:

const amount = 1234567.89;

// Formatting in US dollars
const usd = new Intl.NumberFormat('en-US', { style: 'currency', currency: 'USD' }).format(amount);

// Formatting in Japanese yen
const yen = new Intl.NumberFormat('ja-JP', { style: 'currency', currency: 'JPY' }).format(amount);

console.log(usd); // $1,234,567.89
console.log(yen); // ¥1,234,568

With Intl, you can ensure your app provides the right experience for users worldwide, whether it’s displaying dates, currencies, or handling complex text scripts!
