This is like saying you can't have a favorite type of rectangle because some rectangles are squares. If you're a master of neurosurgery, a reasonable person would also consider that to be a master of medicine. Just as I would expect a master neurosurgeon to not be a master dermatologist but be able to master dermatology much faster than I could as a non-medical person, I would similarly expect a master C++ developer to master Javascript frontend development much faster than a junior dev, let alone a non-software person.
