Video transcript

To add localization in React Native, start by installing the `react-native-localize` and `i18n-js` libraries. Then, create a `locales` directory with JSON files for each language you want to support. Use a `i18n.ts` file to configure the i18n-js library with these JSON files. Finally, wrap your components with the `I18nProvider` and use the `t` function for localized strings. This process enables seamless multilingual support in your React Native app.
