An action is dispatched, the store runs the relevant reducer, the reducer returns new state, and the new state flows to components via useSelector. It is a strict one-way flow that makes state updates predictable.
Because Redux relies on predictable, reproducible state updates for features like time-travel debugging. A pure reducer takes state and an action and returns new state with no side effects, so the same input always produces the same output.
