Here are some common React interview questions along with their answers: 1. What is React? · React is an open-source JavaScript library developed by Facebook for building user interfaces, specifically for single-page applications (SPAs) and interactive UI components. 2. What are the key features of React? · Some key features of React include: · Virtual DOM: React uses a virtual DOM to efficiently update the UI by minimizing DOM manipulations. · Components: React applications are built using reusable components, making it easy to maintain and scale complex UIs. · JSX: JSX is a syntax extension for JavaScript that allows you to write HTML-like code within JavaScript files, making it easier to define UI components. · Unidirectional data flow: React follows a unidirectional data flow architecture, where data flows only in one direction, from parent to child components. 3. What is JSX? · JSX (JavaScript XML) is a syntax extension for JavaScript that allows you to write HTML-like code within JavaScript files. It enables you to define UI components in a more declarative and readable manner. 4. What is the difference between a class component and a functional component in React? · Class components are ES6 classes that extend React.Component and have a state and lifecycle methods. Functional components are simply JavaScript functions that accept props as arguments and return React elements. With the introduction of React hooks, functional components can also have state and lifecycle behaviour. 5. What are React hooks? · React hooks are functions that allow you to use state and other React features in functional components. They enable you to reuse stateful logic without writing class components. Some commonly used hooks include useState, useEffect, useContext, and useRef. 6. What is the purpose of useState hook in React? · The useState hook is used to add state management to functional components in React. It allows you to declare state variables and update them within functional components. 7. Explain the useEffect hook in React. · The useEffect hook is used to perform side effects in functional components, such as data fetching, DOM manipulation, or subscribing to external events. It is like lifecycle methods (e.g., componentDidMount, componentDidUpdate, componentWillUnmount) in class components. 8. What is props drilling in React? · Props drilling refers to the process of passing data from a parent component to nested child components through props. As the application grows, props may need to be passed through multiple intermediary components, resulting in a pattern known as props drilling. 9. What is a higher-order component (HOC) in React? · A higher-order component (HOC) is a pattern in React that involves wrapping a component with another component to enhance its functionality. HOCs are commonly used for code reuse, logic abstraction, and cross-cutting concerns such as authentication and authorization. 10. How does React Router work? · React Router is a library that provides declarative routing for React applications. It allows you to define routes as components and render them based on the current URL. React Router uses the browser's history API to handle navigation and URL changes without full page reloads. These questions cover some fundamental concepts of React that are commonly asked in interviews. Make sure to understand these concepts thoroughly and be prepared to provide examples or elaborate on them during interviews.
