How does Redux Toolkit simplify Redux usage?

Short answer: Redux Toolkit (RTK) is the official, recommended way to write Redux logic. ✅ RTK Benefits: Less boilerplate Built-in createSlice, createAsyncThunk, configureStore Integrated DevTools Handles immutability under the hood ✅

Example code

const counterSlice = createSlice({ name: 'counter', initialState: 0, reducers: { increment: (state) => state + 1, }, }); export const { increment } = counterSlice.actions;

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.
