React Native
1 - What are the key differences between React Native and React?
Answer: React Native uses native components instead of HTML, allowing for a more performant app with a native look and feel.
2) How do you handle state management in React Native?
Answer: Redux is a popular state management library for React Native, providing a centralized store for application state.
3) What are the challenges of developing cross platform apps with React Native?
Answer: Differences in platform APIs and UI elements can pose challenges, requiring platform specific code or third party libraries.
4) How do you optimize performance in React Native apps?
Answer: Use optimized components, lazy loading, and memoization to reduce bundle size and improve rendering speed.
5) What are the best practices for writing reusable React Native components?
Answer: Encapsulate functionality, utilize propTypes, and consider using composition over inheritance.

6) How do you use the React lifecycle to manage component state?
Answer: The lifecycle methods allow you to perform tasks at specific points in a component's lifecycle, such as fetching data on mount.
7) What are the advantages of using hooks in React?
Answer: Hooks simplify state management, reduce the need for class components, and allow for easier code reuse.
8) How do you implement conditional rendering in React?
Answer: Use conditional statements such as if else blocks or the ternary operator to display different UI elements based on props or state.
9) What is the difference between a controlled and an uncontrolled component?
Answer: Controlled components sync their value with the state, while uncontrolled components allow the DOM to maintain their value.
10) How do you handle events in React?
Answer: Use event handlers such as onClick or onInputChange to define behavior when events occur.
11 - What are the best practices for writing performant React components?
Answer: Utilize memoization, batch updates, and avoid unnecessary re renders.
12) How do you use Redux for state management in React?
Answer: Redux allows for centralized state management, providing a single source of truth for application data.
13) What is the difference between props and state in React?
Answer: Props are immutable data passed from parent to child components, while state is internal data managed within a component.
14) How do you handle async operations in React?
Answer: Use lifecycle methods or third party libraries like Axios to fetch data asynchronously or perform side effects.
15) What are the best practices for testing React components?
Answer: Use unit testing frameworks like Jest to test component functionality and isolation.
