What is batched updates in React and how does it enhance performance?
Explain the concept of batched updates in React and how it helps optimize rendering when multiple state updates occur.
Answer
• Batching allows React to group multiple state updates into a single re-render, reducing the number of renders and improving performance. • With batched updates, React calculates the new state and updates the DOM efficiently, minimizing layout thrashing. • Utilizing batched updates can significantly enhance performance in applications dealing with rapid state changes.
