What is the Intl namespace object for?

The Intl namespace object in JavaScript is used for internationalization purposes. It provides language-sensitive string comparison, number formatting, and date and time formatting. For example, you can use Intl.DateTimeFormat to format dates according to a specific locale:

const date = new Date();
const formatter = new Intl.DateTimeFormat("en-US");
console.log(formatter.format(date)); // Outputs date in 'MM/DD/YYYY' format
