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

Improving the performance of a React app can be effectively achieved through lazy loading and code splitting, which help reduce the initial load time by loading components only when they are needed. React's built-in `React.lazy` and `Suspense` make it easy to implement these techniques. import React, { Suspense } from 'react'; const LazyComponent = React.lazy(() => import('./LazyComponent')); function App() { return ( My React App ); } export default App; ADDITIONAL COMMENT: Use `React.lazy` to dynamically import components, which splits the code at the component level. Wrap lazy-loaded components with `Suspense` to display a fallback UI while the component is loading. Consider using React Router's `loadable` components for route-based code splitting. Ensure that your build tool (like Webpack) is configured to handle dynamic imports correctly. Analyze bundle sizes using tools like Webpack Bundle Analyzer to identify further optimization opportunities. ✅

Improving the performance of a React app can be effectively achieved through lazy loading and code splitting, which help reduce the initial load time by loading components only when they are needed. React's built-in `React.lazy` and `Suspense` make it easy to implement these techniques.

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

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

    function App() {
      return (
        <div>
          <h1>My React App</h1>
          <Suspense fallback={<div>Loading...</div>}>
            <LazyComponent />
          </Suspense>
        </div>
      );
    }
    export default App;
    <!-- END COPY / PASTE -->
