```javascript
const addLoggingToDispatch = (store) => {
  const rawDispatch = store.dispatch;
  return (action) => {
    console.group(action.type);
    console.log('prev state', store.getState());
    console.log('action', action);
    const returnValue = rawDispatch(action);
    console.log('next state', store.getState());
    console.groupEnd(action.type);
    return returnValue;
  }
}
```

and later in your code

```javascript
store.dispatch = addLoggingToDispatch(store);
```
