// A prototype-based language has the notion of a prototypical object, an object used as a template from which to get the initial properties for a new object.
//
/**
* Property lookup in Javascript looks within an object's own properties and,
* if the property name is not found, it looks within the special object property __proto__.
* This continues recursively; the process is called "lookup in the prototype chain".
* The special property __proto__ is set when an object is constructed;
* it is set to the value of the constructor's prototype property.
* So the expression new Foo() creates an object with __proto__ == Foo.prototype.
* Consequently, changes to the properties of Foo.prototype alters the property lookup for all objects that were created by new Foo().
