What's Internationalization Libraries for Web Development?

Internationalization (i18n) libraries are essential tools in web development that help developers create applications that can support multiple languages and regions. These libraries provide the necessary functionalities to manage translations, format dates, numbers, and currencies according to the user's locale, ensuring a seamless user experience across different languages. They simplify the process of adapting web applications for global audiences, making it easier to reach diverse user bases.
