1 - What is React Native?
Answer: A JavaScript framework for building native mobile apps for iOS and Android.
2) Why use React Native?
Answer: Enables cross platform app development, reduced development time and cost, and enhanced performance.
3) What are the key components of React Native?
Answer: Components, state management, styles, and networking.
4) What is the difference between a class and a function component in React Native?
Answer: Class components define state and lifecycle methods, while function components are lightweight and accept props.
5) How do you handle state management in React Native?
Answer: Using Redux or Zustand for complex state management, or local state for smaller components.
6) What is the purpose of the Navigator component?
Answer: To handle navigation between different screens within the app.
7) What is the use of the AsyncStorage API?
Answer: To store data locally on the device, such as user preferences or session details.
8) How do you render data from an API in React Native?
Answer: Using the Fetch API or a library like Axios to retrieve data, and then using the `useState` hook to update the component's state with the data.
9) What is the difference between props and state in React Native?
Answer: Props are immutable data passed from a parent component, while state is mutable data managed by the component itself.
10) What are some best practices for optimizing React Native apps?
Answer: Using memoization techniques, optimizing images, and minimizing unnecessary re renders.
11 - What are the advantages of using React Native over native development?
Answer: Code reusability, faster development, and access to a large community and ecosystem.
12) What are some limitations of using React Native?
Answer: Limited access to native features, potential performance issues for complex apps, and dependency on third party libraries.
