React.js ~New feature in React 19.3~

React 19.3 introduces the ViewTransition component, which enables animations for adding, removing, and sizing elements. Developers can implement various animation types, including enter, exit, update, and share, using startTransition. Additionally, React styling guidelines specify image handling based on location. Files in the public folder are served as static assets from the app root, while images within the src folder must be imported to allow the bundler to optimize and transform the assets effectively.
