React Native is a framework developed by Facebook for building mobile applications using JavaScript and React. It allows developers to create cross-platform apps for iOS and Android with native-like performance and user experiences. With features like hot reloading and reusable components, React Native streamlines development while leveraging a large community and ecosystem for support and resources.

Key Features of React Native:

• Cross-platform Compatibility: React Native enables developers to write code once and deploy it on both iOS and Android platforms, saving time and effort.

• Native Performance: By accessing device APIs directly from JavaScript, React Native ensures that applications deliver high performance and native-like user experiences.

• Hot Reloading: React Native offers hot reloading, allowing developers to see changes made to the code in real time without recompiling the entire application, speeding up the development process.

• Component Reusability: React Native promotes a component-based architecture, where UI elements are broken down into reusable components, enhancing code maintainability and scalability.

• Community Support: React Native has a vibrant community of developers and contributors, providing access to a wide range of pre-built components, third-party integrations, and solutions to common development challenges.

• Facebook Backing: React Native is actively maintained by Facebook and has been used in the development of several mobile applications, ensuring ongoing support, updates, and improvements.
