The application will start and can be accessed at http://localhost:3000.
Once the application is running, you can select a language, date format, number format, and units type from the dropdown menus. The application will display a welcome message, a date, a number, and a unit value, all localized according to your selections.
The following scripts are available:
npm start: Starts the development server.npm build: Builds the app for production.npm test: Runs the test watcher in an interactive mode.npm eject: Removes this tool and copies build dependencies, configuration files and scripts into the app directory.
The main entry point of the application is the App component, which uses the useTranslation hook from react-i18next to provide localization. It maintains state for the selected language, date format, number format, and units type, and provides functions to handle changes to these selections.
The App component renders LocalizedDate, LocalizedNumber, and LocalizedUnit components, passing them the relevant format key or units type and a value to display.
To run tests, use the npm test command. The tests use the @testing-library/react package.
