Internationalization and localization in React Native

Internationalization (i18n) and localization (l10n) are key processes in developing mobile applications that adapt to various languages and regions, enhancing accessibility for a global audience. While internationalization involves designing applications to support different locales, localization focuses on translating the app's content to meet specific regional and linguistic needs. The tutorial detailed how to implement localization in both Expo and bare React Native apps using tools like expo-localization and i18n-js, which facilitate the adaptation of app content based on a user's device settings. The process includes setting up the development environment, installing necessary libraries, and configuring the app to display text in multiple languages such as English, Chinese, and Spanish. The guide also demonstrated how to centralize text in a separate file for easier translation management and tested the app's responsiveness to changes in device language settings. The tutorial emphasizes the use of i18n.t() function to render localized content and offers the full code on GitHub, encouraging developers to experiment and improve their apps' international accessibility.
