React Native is a prominent framework for mobile app development that has garnered widespread attention and acclaim. Its significance lies in its ability to streamline the app development process for multiple platforms, such as iOS and Android, by enabling developers to write a single codebase. This cross-platform approach not only saves time and resources but also promotes code reusability, as a significant portion of the codebase can be shared between platforms. The framework boasts features like "Hot Reloading" for rapid development, a vast ecosystem with a supportive community, a declarative syntax that enhances code maintainability, and the option to create custom native modules for platform-specific features.

React Native is a popular open-source framework for building mobile applications, and it is a sibling framework to React, which is used for web application development.
