React Native is an open-source framework developed by Facebook that allows developers to build mobile applications using JavaScript and React. It enables the creation of natively rendered mobile apps for both iOS and Android platforms with a single codebase, offering a more efficient and cost-effective approach compared to traditional native app development.React Native uses React’s declarative syntax and component-based structure, allowing developers to create reusable UI components. However, unlike React for the web, React Native components are rendered using native platform APIs, ensuring that the app feels and performs like a native mobile app.One of the key benefits of React Native is the ability to share most of the code between iOS and Android, which reduces development time and resources. Additionally, React Native allows developers to integrate native modules when performance-intensive operations are required, ensuring a seamless user experience.In summary, React Native bridges the gap between web development and mobile app development by using JavaScript and React, enabling faster development and a more unified approach for building cross-platform mobile applications.
