React Native is a cross-platform mobile development framework that enables the creation of native mobile applications using JavaScript and React. It allows developers to build applications for iOS and Android simultaneously, sharing a substantial portion of codebase, which enhances development efficiency. React Native leverages a declarative syntax and component-based architecture, similar to React, providing a familiar and efficient development experience. This framework is renowned for its ability to deliver high-performance, native-like user experiences while streamlining the development process for mobile applications.
