Prototype-based programming is a style of object-oriented programming in which classes are not present, and behaviour reuse (known as inheritance in class-based languages) is performed via a process of cloning existing objects that serve as prototypes. This model can also be known as classless, prototype-oriented or instance-based programming. Delegation is the language feature that supports prototype-based programming.
Prototype / Archetype
The Nodal Model combines these two concepts, since instances are based on prototypes, but the prototypes evolve over time from feedback from the instances "in the field". This is a tangled hierarchy where each is based on the other, but as with all such "paradoxes" found in such systems they are resolved by each direction of influence operating on a different scale of time - i.e. local instances maintain a dynamic real-time relationship with the global prototype which changes very slowly as the information from many instances is collated and assessed.
