Why does React use a virtual DOM instead of updating the real DOM directly?

  • To ensure compatibility with older browsers.
  • To increase the size of JavaScript bundles.
  • To make the codebase more complex.
  • To simplify development and improve performance.
React uses a virtual DOM to simplify development and improve performance. By working with a virtual representation of the DOM, React can minimize direct manipulation of the real DOM, reducing the risk of bugs and improving performance by batching updates. This approach doesn't aim to make the code more complex, ensure compatibility with older browsers, or increase bundle size.
