One way to approach prototypical inheritance is parasitic inheritance, Crockford's first pattern.

Parasitic inheritance is similar to parasitic constructors and factory patterns. Create a function that implements inheritance, enhances the object in some way, and then returns the object.

Parasitic inheritance is suitable for scenarios that focus primarily on objects and do not care about types and structural functions.

Object.create() need not be used here; any function that returns a new object (including original methods and properties) can be used here.

examples

function createAnother (original) { const clone = Object.create(original) clone.sayHi = function () { console.log('Hi! ') } return clone} const person = { name: 'wzq', friends: ['zmk', 'gjx', 'wz']} const anotherPerson = createAnother(person)anotherPerson.sayHi() //Hi!
