Primitive Method
“When it comes to subclassing, knowing which methods are ‘primitive’ methods is important.
The notion of primitive methods are those methods form the basis of the public interface/class.
The rest of the methods are just convenience methods built around them. When overriding a
class behavior with subclassing, just overriding those primitive are often enough.” Ref[1]
