Prototypal inheritance in JavaScript as described by Douglas Crockford

prototypal-inheritance-crockford

Prototypal inheritance in JavaScript is described by Douglas Crockford as: you make prototype objects, and then ... make new instances. Objects are mutable in JavaScript, so we can augment the new instances, giving them new fields and methods. These can then act as prototypes for even newer objects. We don't need classes to make lots of similar objects....Objects inherit from objects. What could be more object oriented than that?

DIFFERENT but related:

Advantages to using the "new" keyword for prototypal inheritance AKA "classical model" AKA "constructor pattern" VERSUS the "prototypal pattern" via Object.create:

• the "new" keyword / constructor pattern is simply more widely recognized
• "new" keyword / constructor pattern provides instanceof support whereas such support has to be hacked in with prototypal pattern via Object.create()
