index.js

var Person = require('./person')
var sean = Person.create('Sean Hagstrom', 20)
 
console.log(sean.name) // Sean Hagstrom
console.log(sean.age) // 20

person.js

var wrap = require('./wrap')
 
function Person(name, age) {
  this.name = name
  this.age = age
}
 
module.exports = wrap(Person)

wrap.js

function wrap(constructor) {
  return {
    create: function() {
      var object = Object.create(constructor.prototype)
      return constructor.apply(object, arguments) || object
    }
  }
}
 
module.exports = wrap
