1 - Explain React Native's architecture and how it differs from native development.
React Native uses a JavaScript bridge to communicate with native code, allowing for cross platform development. It differs from native development by using a declarative UI approach and a single codebase for multiple platforms.
2) Describe the differences between state and props in React Native.
State is local and can be modified within a component, while props are passed down from a parent component and cannot be modified.
3) Explain how you would debug a performance issue in React Native.
Use tools like React Native Debugger, Chrome Developer Tools, and React Native Profiler to identify bottlenecks in rendering or memory usage.
4) Discuss the lifecycle methods of a React Native component.
Lifecycle methods allow components to respond to changes in their state or props, such as `componentDidMount`, `componentWillUnmount`, and `shouldComponentUpdate`.
5) Explain how to handle asynchronous operations in React Native.
Use promises, async/await, or state management libraries like Redux to manage asynchronous operations and update the UI accordingly.
6) Describe how React Native supports platform specific functionality.
React Native provides platform specific modules and APIs, allowing developers to access native functionality on iOS and Android.
7) Explain the advantages of using a state management library like Redux in React Native.
Redux provides a centralized store for application state, making it easier to manage and avoid inconsistencies.
8) Describe how you would handle navigation in a React Native application.
Use libraries like React Navigation or NativeStack to manage screen transitions and navigation state.
9) Explain the performance optimizations you would consider when developing a React Native application.
Optimize by using lazy loading, caching, and optimizing rendering by using PureComponents or memoization.
10) Discuss the security considerations when developing a React Native application.
Use SSL/TLS for network requests, secure storage for sensitive data, and avoid exposing sensitive information in debug logs.
11 - Explain the importance of testing in React Native development.
Testing ensures the reliability and stability of the application by identifying bugs and errors.
12) Describe the different testing tools and techniques available for React Native.
Use unit testing frameworks like Jest, snapshot testing, and integration testing tools like Detox.
13) Explain how you would deploy a React Native application to the App Store and Play Store.
Prepare the app for deployment, generate app bundles, and follow platform specific requirements for submitting and publishing to the stores.
14) Describe the challenges and solutions for internationalization in React Native.
Use libraries like react native localize and react native i18n to support multiple languages and handle localization of UI elements.
15) Explain how you would approach accessibility considerations in a React Native application.
Use accessibility APIs like `AccessibilityInfo` and provide accessible UI elements, such as screen readers and keyboard navigation.
