Using the this scope is not bad practise it is just very loose, ie it
does not check data types etc.. That is why many people (including
myself) use it very rarely. Another reason is that this data is
intrinsically attached to the object you create whereas you can set
the result of a function call equal to a function call and then you
can use it for whatever you like.
So in summary there is nothing wrong with the this scope just that it
goes against the grain of many OOP principles.
For your above problem I would suggest returning a structure, or set
then in the variables scope within the object and return them using
separate getter methods.
I hope that clears some of it up for you.
