React Native is a widely-used framework for developing mobile applications. It allows developers to build cross-platform apps using JavaScript, a high-level programming language.
JavaScript is the primary programming language used in React Native app development. It is a versatile language known for its ease of use and widespread adoption. With JavaScript, developers can write code that runs on both Android and iOS platforms, saving time and effort in the development process.
In addition to JavaScript, React Native also supports native languages for platform-specific development. For Android, developers can use Java or Kotlin, which are the standard languages for Android app development. These languages provide direct access to Android features and libraries, allowing developers to create apps with native-like performance and functionality.
Similarly, for iOS development, React Native supports Objective-C and Swift. Objective-C was the primary language used for iOS development before the introduction of Swift. However, Swift has gained popularity in recent years and is now the recommended language for iOS app development. By supporting both Objective-C and Swift, React Native allows developers to leverage existing iOS code and libraries, making it easier to develop iOS apps with native capabilities.
By supporting multiple programming languages, React Native provides developers with the flexibility to choose the language that best suits their expertise and project requirements. This flexibility, combined with its cross-platform capabilities, makes React Native a preferred choice for building mobile applications.
