This is a React application entry file. It does the initial setup and imports boilerplate code necessary for the application. This includes importing polyfills for stability and compatibility with IE11, setting up the Redux store for state management with the Provider from react-redux, and establishing consistent styling with sanitize.css.

The application utilizes react-helmet-async for managing changes to the document head, makes use of a root app component named App from the 'app' directory, and sets up internationalization with i18n.

Hot reloadable translation for i18n files and vital report for app performance are also configured in the application.

The application is then rendered into a DOM element with the id of 'root'.
