- Redux fits large apps that need predictable, inspectable state changes.
Redux, rewritten
Classic Redux meant action constants, action creators, switch statements and immutable updates by hand. Redux Toolkit is the official way to write Redux now, and it removes almost all of that.
It remains a strong choice when many features share complex state, when you want time-travel debugging, or when a team values strict, predictable update flows.
