Я пытаюсь вернуть массив в react-redux, но получаю неопределенность, когда пытаюсь получить их в своем компоненте реакции.

Как вернуть массив, используя случаи "GET_TODO", "GET_FINISHED", "GET_LATER".

Редуктор ( GET_ должен возвращать массив )

const initialState = {
  today: [1, 2, 3],
  finished: [3, 2, 1, 3],
  later: [2, 3, 1, 4, 2, 5]
};

export default (state = initialState, action) => {

  switch (action.type) {

    case 'ADD_TODO':
      return [...state.today, action.payload]
    case 'DELETE_TODO':
      return state.today.filter((item, index) => index !== action.payload)
    case 'GET_TODO':
      return state.today
    case 'ADD_LATER':
      return [...state, action.payload]
    case 'DELETE_LATER':
      return state.filter((item, index) => index !== action.payload)
    case 'GET_LATER':
      return [...state.later]
    case 'ADD_FINISHED':
      return [...state, action.payload]
    case 'DELETE_FINISHED':
      return state.filter((item, index) => index !== action.payload)
    case 'GET_FINISHED':
      return [...state.finished]
    default:
      return state;
  }
}

Реагировать компонент

componentDidMount() {
    this.props.get();
  }

mapStateToProps и mapDispatchToProps

function mapStateToProps(state) {
  return {
    today: state.important.today ? state.important.today : [],
    finished: state.important.finished ? state.important.finished : [],
    later: state.important.later ? state.important.later : [],

  }
}

function mapDispatchToProps(dispatch) {
  return {
    add: (value) => {
      dispatch({ type: 'ADD_TODO', payload: value })
    },
    remove: (index) => {
      dispatch({ type: 'DELETE_TODO', payload: index })
    },
    get: () => {
      dispatch({type:'GET_TODO'})
    },
    addToFinished: (value) => {
      dispatch({ type: 'ADD_FINISHED', payload: value })
    },
    removeFinished: (index) => {
      dispatch({ type: 'DELETE_FINISHED', payload: index })
    },
    addToLater: (value) => {
      dispatch({ type: 'ADD_LATER', payload: value })
    },
    removeLater: (index) => {
      dispatch({ type: 'DELETE_LATER', payload: index })
    }
  }
}
