I forgot to wrap the store. So I want the computed property to be in the store so I can just call store.b. Instead of having to write the computed ref seperately. So I think I'll need to do it the 'c' way. As the computed ref should be refering to a reactive object, but in the initilization state, the reactive object has not been created yet.

And yea, the proper way would be to use a proper store management system, but I was wondering if there's an easy way for it.
