JavaScript: Prototype Chain
A object's parent of parent of parent etc forms a chain. This is called a prototype chain.
Note: the prototype chain is never circular, and is impossible to create circular prototype chain.
Note: not all objects have a parent, but buildin objects do (except Object.prototype, which is the root, having parent of null).
You can creat a object without parent by Object.create(null).
