edit, following 2cond comment:

calling gs function javascript (or other language) script not google script (gs) not possible if consider using function...

what can - depending on data function must handle - deploy script webapp running service , call service external app using equivalent of urlfetch (that's service doing in gs).

the service have url can add parameters , return result can use in local app.

note url have use in "versioned" 1 ending .exec (not sure word correct mean published url corresponds version of script , not ".dev" 1 one can use test script in gs).

you'll find details in the documentation , on many other ressources, including so. url typically :
