React Native allows developers to build mobile apps using JavaScript and React which results in a single codebase that can target both Android and iOS platforms. It has advantages like increased productivity through code sharing and hot reloading. Some challenges include needing to update for native SDK changes and interacting with other native apps. Several large companies like Walmart, Airbnb, and SoundCloud use React Native due to benefits like faster development and the ability to share frontend code while keeping business logic on the web.
