Features: Zero Configuration: It sets up Webpack, Babel, ESLint, and other essential tools. Development Server: Provides a development server with hot reloading. Production Build: Automates production optimizations like minification, asset optimization, etc. How to Use CRA: npx create-react-app my-app cd my-app npm start With CRA, you don’t have to manually configure Webpack or Babel. It gives you everything you need to start building React applications right away. Real-world example (ShopNest) ShopNest’s storefront is React: components for ProductCard, CartDrawer, and CheckoutForm, with hooks for local UI state. Say this in the interview Define — one clear sentence (the short answer above). Example — relate it to a project like ShopNest or your real work. Trade-off — when you would not use it.
