Encapsulation involves the packaging of representations by focusing on the hiding ofdetails to facilitate abstraction, where specifications are used to describe whatanentity is and what an entity does and implementations are used to describe how anentity is realized.Inheritance involves the ...
is the way abstraction is applied. a common practice in oop is to limit abstraction to the strict useful minimum for the problem at hand. in oop, premature abstraction is often considered a fault, much as premature optimization. in fp, on the other hand, abstraction is generally pushed as ...
