Classical and prototypal inheritance are fundamentally and semantically distinct.
There are some defining characteristics between classical inheritance and prototypal inheritance. For any of this article to make sense, you must keep these points in mind:
In class inheritance, instances inherit from a blueprint (the class), andcreate sub-class relationships. In other words, you can’t use the class like you would use an instance. You can’t invoke instance methods on a class definition itself. You must first create an instance and then invoke methods on that instance.
In prototypal inheritance, instances inherit from other instances. Usingdelegate prototypes (setting the prototype of one instance to refer to anexamplar object), it’s literally Objects Linking to Other Objects, orOLOO, as Kyle Simpson calls it. Using concatenative inheritance, you justcopy properties from an exemplar object to a new instance.
