This question explores Web Development and addresses practical considerations related to: How can I improve the performance of a React app using lazy loading and code splitting?

Improving the performance of a React app using lazy loading and code splitting involves breaking down your application into smaller chunks that can be loaded on demand, reducing the initial load time. React's `React.lazy` and `Suspense` are commonly used for this purpose. import React, { Suspense, lazy } from 'react'; const LazyComponent = lazy(() => import('./LazyComponent')); function App() { return ( ); } export default App; ADDITIONAL COMMENT: Use `React.lazy` to dynamically import components only when needed. Wrap lazy-loaded components with `Suspense` to handle loading states. Consider using a tool like Webpack for code splitting to automatically split bundles. Analyze bundle size and loading times using tools like Webpack Bundle Analyzer. Ensure that lazy loading is applied to non-critical components to optimize user experience. ✅

Improving the performance of a React app using lazy loading and code splitting involves breaking down your application into smaller chunks that can be loaded on demand, reducing the initial load time. React's `React.lazy` and `Suspense` are commonly used for this purpose.

<!-- BEGIN COPY / PASTE -->
    import React, { Suspense, lazy } from 'react';

    const LazyComponent = lazy(() => import('./LazyComponent'));

    function App() {
      return (
        <div>
          <Suspense fallback={<div>Loading...</div>}>
            <LazyComponent />
          </Suspense>
        </div>
      );
    }

    export default App;
    <!-- END COPY / PASTE -->
