Sometimes you need more than a standard website, so that you can give a unique user experience to your customers. How about in-flight entertainment, retail store kiosk tablets? In that case, there is a great solution available - decoupled Drupal with React.
React and Drupal can be used together to create amazing digital experiences. Just imagine having an admin interface for your website content (Drupal), a stunning responsive front-end (React) and a iOS and Android app downloadable from App Store and Play Store (React Native) using the same data as your website.
This is one of the advantages of decoupled Drupal with React.
