Is it OK to use a local variable and call this in every function or... ?

Question

Which is better?

1. Only once,  initial a GLOBAL variable, e.g.  'userService' with the BuildUserService(). And use that GLOBAL variable in every function where you need to call a UserService.

or

2. In each and every function where you need to call a UserService, initial a LOCAL variable, e.g.  'userService' with the BuildUserService(). And use that LOCAL variable to call the UserService.

NOTE: Is it OK to use example 2 and repeatedly initialize the UserService? 

e.g. UserService userService = sp.BuildUserService();

Hi

If you have requirement where you have to pass meta information like AddJSONDoc/orderBy etc on method call, it is advisable to use different userService reference for each call. However if your method calls do not use these meta info, you can have global reference for the same. Since App42 APIs provides meta info to be passed along with the call to over load its behavior, it is better to use local reference wherever needed to avoid any confusion.

Let me know if it helps

Thanks,

Then how do I know which calls DO pass meta info and which calls DON'T pass meta?
