Lazy loading and code splitting in React help improve performance by loading only the necessary code when it's needed, reducing initial load time.

Lazy Loading with React.lazy and Suspense:

React provides the React.lazy() function to dynamically import components. Combined with Suspense, it allows components to load only when they are rendered.

• React.lazy() tells React to load the component asynchronously.

• Suspense wraps the lazy component and displays a fallback UI while it’s loading.

Code Splitting with React Router:

Code splitting can also be applied with routing, where each route loads only the code it needs

Benefits:

• Reduces initial bundle size.

• Speeds up load times.

• Improves user experience, especially in large applications.

Note: Ensure error boundaries are used to handle potential loading errors gracefully.
