Technical Questions:
1 - Describe the difference between state and props in React and their usage.
State holds the data and logic within a component, while props are immutable and passed down from parent components.
2) Explain the purpose of the render() method in React.
The render() method returns the JSX (JavaScript XML) representation of the component's UI.
3) What is the lifecycle of a React component?
Mounting (constructor, render, componentDidMount), Updating (render, componentDidUpdate), Unmounting (componentWillUnmount)
4) How do you handle asynchronous tasks in React?
Using promises, async/await, or a state management library like Redux.
5) Explain the concept of one way data flow in React and its benefits.
Data flows down from parent to child components, only parent components can update data, promoting unidirectional updates and preventing inconsistencies.
6) What are controlled and uncontrolled components in React?
Controlled components have their values set by React, while uncontrolled components have their values set by the DOM.
7) Discuss the advantages of using Redux for state management in React applications.
Centralized state, immutability, time travel debugging, and easier testing.
8) Explain the difference between class based and functional components.
Class based components use the ‘this’ keyword and have lifecycle methods, while functional components are simpler and use hooks.
Behavioral Questions:
9) Describe a project where you used React and the challenges you faced.
10) How do you approach debugging complex React applications?
11 - What best practices do you follow when developing React applications?
12) How do you stay updated with the latest React developments?
13) Explain how you would design a scalable React application for a large user base.
14) How do you handle performance optimizations in React applications?
15) What is your experience with testing React components?
