| Suggested solution: 
 | |
| 
 | |
| ```javascript
 | |
| const ADD = 'ADD';
 | |
| 
 | |
| function addMessage(message) {
 | |
|   return {
 | |
|     type: ADD,
 | |
|     message: message
 | |
|   };
 | |
| };
 | |
| 
 | |
| 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);
 | |
|     }
 | |
|   }
 | |
| };
 | |
| ```
