What Is React Native

React Native is an open-source framework that lets you build iOS and Android applications using JavaScript and React. Instead of maintaining separate codebases for each platform, you can create mobile apps from a single codebase while still using native UI components and device features. This approach speeds up development and simplifies maintenance without sacrificing the native app experience.

Cross-platform development is the process of building applications that can run on multiple operating systems with a single codebase. With React Native, you can target both iOS and Android without duplicating your work. JavaScript, the language behind React Native, is widely used and familiar to many developers, which lowers the barrier to entry for mobile development. By using JavaScript, you can also reuse logic from web applications, leverage a vast ecosystem of libraries, and benefit from rapid prototyping and iteration. This combination of cross-platform capability and JavaScript’s flexibility makes React Native a compelling choice for modern mobile app development.
