How do you pass data using React Context?

Short answer: ✅ Create context: const ThemeContext = React.createContext(); ✅ Provide context: <ThemeContext.Provider value="dark"> <App /> </ThemeContext.Provider> ✅ Consume context: const theme = useContext(ThemeContext);

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

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
