Mam store.js
plik
import { createStore, combineReducers } from "redux";
import reducerADD from "../reducer/reducerADD"
export const store = createStore(combineReducers({ reducerADD}));
Kiedy zmieniam format w store.tsx
, pojawia się błąd:
No overload matches this call.
Overload 1 of 2, '(reducers: ReducersMapObject<{ reducerADD: { lastName: string; firstName: string; password: string; email: string; }[]; }, any>): Reducer<{ reducerADD: { lastName: string; firstName: string; password: string; email: string; }[]; }, AnyAction>', gave the following error.

Types of parameters 'state' and 'state' are incompatible.

Jaki jest tego powód?
const reducerADD = (state = [], action:action) =>{ switch (action.type) { case "ADD": return [...state, ...[action.add]]; default: return state; } }
reducerADD
?
