React Native, initially launched by Facebook in 2015, has become a popular framework for building native mobile apps using the React library, despite some skepticism following Airbnb's discontinuation of its use in 2018. The framework is favored for its cross-platform capabilities, allowing developers to share up to 95% of code across Android and iOS, and its declarative UI and component-based architecture, which enhance predictability and reduce bugs. Major tech companies like Microsoft, Pinterest, and Spotify have adopted React Native, and recent additions like the Hermes JavaScript engine and Fast Refresh debugging tool have improved performance and developer experience. React Native's future looks promising with ongoing architectural changes aimed at enhancing performance, including a new JavaScript Interface and renderer, which are expected to bring it closer to native frameworks in terms of efficiency and user experience. The framework's active community and continuous improvements underscore its viability and growth potential in the mobile app development landscape.
