Adding Object to empty array in redux toolkit

Question

guys how to append an object to an empty array in redux toolkit? I have set a currentTimeOfServices:[] in my slice then I dispatch an action with a payload dispatch(userActions.getCurrentTime({ startTime: startTime, name: item })); In my getCurrenTtime reducer I don't understand how to append this item.

getCurrentTime: (state, action) => {
      state.currentTimeOfServices = [
        ...state.currentTimeOfServices,
        { startTime: action.payload.startTime, name: action.payload.name },
      ];
    }

This is wrong and I know that but I want to know how to add/append an object to this currentTimeOfServices empty array?

Redux Toolkit uses Immer inside, which lets you "mutate" the existing state with normal JS syntax. So, all you need is:

state.currentTimeOfServices.push(newItem)

What you've got there is valid for a hand-written immutable update, but it's not necessary here.

See the docs for more details:
