If the object is the same instance than before, it is not better to update it persΓ©, it depends, the garbage collector will delete unused pointers so no pain in reassign it, depending of the application making an update/copy method can be so much elaborated, even more if you are receiving info fetching api requests.
I do the same as Curtis, always const until i need to reassign the variable.
