reducer.js
```js
import rpr from "../../_redux/reducerPathResolver";
//...
export const modalVisibilitySelector = (state: any) => state[rpr[reducerResolverKey]].show
export const reducerResolverKey = 'modal'
```

reducerPathResolver.js
```js
import { reducerResolverKey as modal } from "../_utils/Modal/reducer";
export default {
  [modal]: 'modal'
}
```

rootReducer.js
```js
import modalReducer, { reducerResolverKey as modal } from '../_utils/Modal/reducer';

export const rootReducer = combineReducers({
  [rpr[modal]]: modalReducer,
})

export const getSelectedPerson = (state: any) => state.selectedPerson
```

use Reducer path resolve solution to make better selectors

- [ ] make sure there is no repetition key in `reducerPathResolver`, set up a function to validate it
