suppose I have a Vuex store: with such a structure

https://jsfiddle.net/liqi0816...</a>

root
 people: { name }
  age: { value }
  gender: { value }
 this structure actually has dependencies,  age  and  gender  depend on  people . If  people  changes,  age  and  gender  should at least reset to an uninitialized state. The question now is, how do you write the  "?"  in the above code? Try .. / , which is not supported. 
 this is a simplified problem. In the actual project,  age  and  gender  are very large, so it is impossible to cancel  namespaced . Or should not have used module? in the first place? 
 further, what should I do if  people  is registered dynamically and it is impossible to know the path name of  people  in advance? 
 Thank you
