What is internationalization, and how does it apply to a Next.js application?

Internationalization means preparing your application to support multiple languages and regions, such as translating text and formatting dates or currency differently depending on the visitor's locale. In Next.js, this usually involves structuring your routes and content so each supported language has its own clearly organized version.

// app/[locale]/page.js
export default function HomePage({ params }) {
  return <h1>Welcome</h1>; // translated based on locale
}
