There Are Three Kinds of Prototypal OO
- Concatenative inheritance: The process of inheriting features directly from one object to another by copying the source objects properties.
- Prototype delegation: If a property is not found on the object, the lookup is delegated to the delegate prototype, which may have a link to its own delegate prototype, and so on up the chain until you arrive at `Object.prototype`, which is the root delegate.
- Functional inheritance: In JavaScript, any function can create an object. When that function is not a constructor (or `class`), it’s called a factory function.
