      Top 5 Technical Interview Questions Asked React Developer

      • Explanation: The Virtual DOM is a lightweight JavaScript object which is a copy of the real DOM. When the state of an object changes, React updates the Virtual DOM rather than the real DOM. React then compares the Virtual DOM with a snapshot of the previous Virtual DOM and efficiently updates only the elements that have changed in the real DOM, making the update process fast and minimizing direct manipulation of the DOM.
      • Why it’s asked: This question tests your understanding of React’s core concept that contributes to its performance efficiency.
      • Explanation: In React, state refers to the internal data of a component, which can change over time. Props (short for “properties”) are read-only attributes passed to a component by its parent component. While state is managed within the component and can be modified by the component itself, props are immutable and meant to be passed down to child components.
      • Why it’s asked: This is a fundamental concept in React, and understanding the difference between state and props is essential for managing data flow and component interaction.
      • Explanation: React Hooks allow you to use state and other React features in functional components. useState is a hook that lets you add state to a functional component, while useEffect is used for performing side effects in function components, such as data fetching, subscriptions, or manually changing the DOM.
      • Why it’s asked: Hooks are a relatively newer addition to React, and being able to use them effectively demonstrates that you are up-to-date with modern React practices.
      • Explanation: Common techniques include using React’s memo to prevent unnecessary re-renders, lazy loading components with React.lazy and Suspense, optimizing state management, avoiding inline functions in render, using efficient algorithms for list rendering, and leveraging server-side rendering (SSR) with frameworks like Next.js.
      • Why it’s asked: Performance is critical in web applications, and this question checks your ability to write efficient, scalable code.
      • Explanation: In a controlled component, form data is handled by the component’s state. The state updates as the user inputs data, making the component the single source of truth. In contrast, uncontrolled components store their own state internally, and you query the DOM using refs to retrieve the value when needed.
      • Why it’s asked: This question tests your understanding of form management in React, which is a common task in many applications.
