Keine Überlastung entspricht diesem Aufruf. Überladung 1 von 2,

Ich habe store.jsDatei

import { createStore, combineReducers } from "redux";
import reducerADD from "../reducer/reducerADD"

export const store = createStore(combineReducers({ reducerADD}));

Wenn ich das Format in ändere store.tsx , wird ein Fehler angezeigt:

No overload matches this call.

Was ist der Grund dafür?

Der Staat muss etwas stärker typisiert werden. Es wird versucht, Ihren Ausgangszustand von Typ anyzu Typ umzuwandelnnever .

Wenn Sie den Standardstatus für die Daten erstellen, sollten Sie eine Schnittstelle für Ihren Status definieren. Hier ein Beispiel für ein Aufgabenlistenarray:

interface IAppState {
  toDoList: any[];
}
const initialState: IAppState = {
  toDoList: []
};

export default function reducer(state = initialState, action) {}
