1 - Explain React Native's architecture.

React Native uses a JavaScript bridge to communicate between native code and the React Native environment, allowing developers to build cross platform mobile apps using JavaScript.

2) Describe Flexbox in React Native.

Flexbox is a layout system used in React Native to position and align UI elements. It controls properties such as flex direction, flex, justifyContent, and alignItems.

3) What are the benefits of using React Native?

React Native's primary benefits include:

  Cross platform development

  Improved developer experience

  Native performance

  Large community support

4) How do you handle state management in React Native?

State management can be handled in React Native using state hooks (useState and useEffect), Redux, or third party libraries like MobX or Recoil.

5) Explain the purpose of the render() method.

The render() method in React Native is responsible for defining the UI structure and returning a React element to be rendered on the screen.

6) What is the difference between props and state?

Props (properties) are immutable values that are passed down to child components, while state is mutable and can be modified within the component.

7) How do you style components in React Native?

Styling in React Native can be done using inline styles, StyleSheet objects, or CSS in JS libraries like styled components.

8) Describe the use of React Navigation.

React Navigation is a library used for managing navigation and screen transitions in React Native applications.

9) How do you handle asynchronous operations in React Native?

Asynchronous operations can be handled using Promises, async/await, or React Native's built in AsyncStorage for persistent storage.

10) What is the purpose of expo and expo cli?

Expo is a framework that simplifies React Native development by providing pre built tools and libraries, while expo cli is a command line interface used to manage Expo projects.

11 - How can you optimize React Native performance?

React Native performance can be optimized by techniques such as using PureComponents, lazy loading, and profiling.

12) Explain the concept of hot reloading in React Native.

Hot reloading allows developers to make live changes to their code while the app is running, without having to rebuild the entire app.

13) What is the difference between a functional component and a class component?

Functional components are simple functions that accept props and return JSX, while class components use ES6 classes and have lifecycle methods.

14) How do you debug React Native apps?

React Native apps can be debugged using tools such as the Chrome debugger, the React Native DevTools, or by printing console logs.

15) Describe the importance of open source libraries in React Native development.

Open source libraries play a vital role in React Native development by providing pre built components, tools, and utilities that enhance app functionality and accelerate development.
