Classical inheritance is based on a strict class hierarchy with clear parent-child relationships. Prototypal inheritance is more flexible and allows for more dynamic and ad-hoc object relationships.
Classical inheritance involves creating instances of predefined classes. Prototypal inheritance involves cloning or extending existing objects to create new objects.
Classical inheritance can be less flexible due to the rigid class hierarchy and compilation-time definitions. Prototypal inheritance offers greater flexibility and adaptability, allowing objects to be easily modified and extended at runtime.
