  }; 
 }; 
 
 function messageReducer (previousState, action) { 
  return [...previousState, action.message]; 
 } 
 
 let store = { 
  state: [], 
  getState: () => store.state, 
  dispatch: (action) => { 
    if (action.type === ADD) { 
      store.state = messageReducer(store.state, action); 
    } 
  } 
 };
