More FAQs in Redux Actions vs Reducers vs Slices: The Modern Mental Model
Actions are objects describing what happened. Reducers are functions that take state and an action and return new state. Slices bundle state and reducers for one feature together. In RTK, createSlice auto-generates actions from your reducers.
A collection of state and reducers for one feature, bundled together. A cart slice holds cart state and the reducers that update it. Slices are the RTK way to organize Redux by feature instead of by file type.
Yes. createSlice auto-generates action creators from your reducers, so you do not hand-write action types and creators as in classic Redux. You define the reducer, and RTK creates the action creator with the same name.
