I didn’t go into that as it was even further off-topic, but since you have brought it up;
the key difference is with inheritance is a Dog that inherits Animal IS an Animal, with composition a Dog contains Animal, it is not an Animal. It’s a big difference but easily overlooked, that translates practically to inheritance being a higher level concept and composition being quite fundamental.
Inheritance is mostly a fault of human thinking, all uses can be practically replaced by composition while making data relationships simpler.
