What is React Fast Refresh?

With the introduction of React Fast Refresh, developers can enjoy improved developer experience and better debugging capabilities compared to its predecessor, React Hot Loader. This new feature automatically reloads pages with syntax or runtime errors resolved, and provides full page reload when updates are made outside of the React tree. It also preserves state across re-renders and handles errors better, making it a game-changer for complex applications such as games, user preferences, forms, and client-side navigation.
