1 - Why React Native for mobile development?
React Native leverages JavaScript and React, enabling cross platform app development for iOS and Android. It offers native like performance, reducing the time and cost of mobile app development while maintaining a consistent user experience.
2) Explain the React Native architecture.
React Native employs a modular architecture. JavaScript code runs on the UI thread, while native code handles platform specific tasks. The “bridge” component communicates between the two, facilitating data transfer.
3) How does React Native handle state management?
React Native uses the Flux pattern, where unidirectional data flow and immutable state updates ensure predictable and reliable app behavior. Flux libraries like Redux and MobX help maintain complex state management.
4) Describe your experience with React Native navigation.
React Native provides multiple navigation options, including Navigator, StackNavigator, and TabNavigator. It enables seamless navigation and screen transitions while maintaining app state consistency.
5) How do you optimize React Native apps for performance?
To optimize performance, consider optimizing JavaScript code, using native modules for heavy computations, employing lazy loading and caching techniques, and leveraging performance monitoring tools.
6) What are the best practices for styling React Native apps?
Best practices for styling include using inline styles, CSS in JS libraries (e.g., styled components), and adopting a consistent and modular approach to ensure maintainability.
7) How do you manage asynchronous operations in React Native?
React Native provides async/await syntax and libraries like RxJS for handling asynchronous operations. Proper error handling and lifecycle management are crucial to prevent unexpected app behavior.
8) What is the purpose of Props and State in React Native?
Props are immutable values passed from parent to child components, providing data to child components. State, on the other hand, is mutable and internal to the component, allowing it to manage its own data and behavior.
9) How do you debug React Native apps?
Debugging techniques include using console.log statements, Chrome DevTools (via Remote Debugging), React Native Debugger, and third party debugging tools like Reactotron.
10) What is the role of the “native modules” in React Native?
Native modules allow developers to access platform specific functionality (e.g., camera, GPS) from within React Native code. They are typically written in Java (Android) or Objective C (iOS).
11 - Discuss the advantages and disadvantages of using Redux for state management.
Redux provides a structured and predictable way of managing state in React Native apps. However, it can introduce more complexity and boilerplate code, and may not be suitable for very small or simple apps.
12) How do you handle animations in React Native?
React Native offers built in animation APIs like Animated, which enables developers to create complex and performant animations. Third party libraries like Lottie provide additional animation options.
13) What are the key differences between React Native and Flutter?
React Native uses JavaScript while Flutter uses Dart. Flutter uses a Skia 2D rendering engine for native like UI, while React Native leverages platform specific UI components. Flutter has a smaller codebase size, but React Native has a broader community and more mature tooling.
14) How can you improve the accessibility of React Native apps?
Accessibility features include adding labels to components, supporting assistive technologies like screen readers, and ensuring that color combinations and font sizes are accessible to users with visual impairments.
15) What are some resources for learning and staying updated on React Native?
Useful resources include the React Native documentation, online courses (e.g., Udemy, Coursera), community forums (e.g., Stack Overflow, Reddit), and attending industry events and conferences.
