A cross platform app development framework used to create native like mobile applications using JavaScript.
2) Advantages of using React Native?
Reusable code, faster development, native performance, and cross platform compatibility.
3) Explain the architecture of React Native?
Consists of a JavaScript engine (JavaScriptCore) and native modules (written in Objective C/Swift for iOS and Java for Android).
4) What is the difference between a state and a prop in React Native?
State is used for local component data that can change, while props are used for data passed from parent to child components.
5) What is the use of the FlatList component?
A component used to render a vertically scrolling list of data items in a performant way.
6) Explain the concept of declarative UI in React Native.
Describes the UI as a function of its state, allowing for easier and more maintainable code.
7) What are some popular libraries used in React Native development?
Expo, React Navigation, Redux, and Axios.
8) Describe the debugging process in React Native.
Uses Chrome DevTools or the React Native Debugger tool.
9) What is the difference between a class and a functional component in React Native?
Class components allow for lifecycle methods and state management, while functional components are stateless and use hooks.
10) How to handle navigation in React Native?
Use the React Navigation library to manage screen transitions and navigation stacks.
11 - What is the purpose of the AsyncStorage API?
Provides a way to store and retrieve data asynchronously on the device.
12) Explain the use of the fetch API in React Native.
