weird part 63 — object.create and pure prototypal inheritance

#Object.create()

var person = {
 firstname : 'Default',
  lastname: 'Default',
  year : 1984,
  age : function(){
   return 2018 - this.year;
  },
  greet : function(){
   return 'hello ' + this.firstname;
  }
}
var john = Object.create(person);
console.log(john)
john.firstname = 'John';
john.lastname = 'Doe';
console.log(john.greet())
console.log(john.age())

• Object.create(prototypeObject, propertyObject)

# comparison with function constructor

const Person = function(firstname, lastname, year){
this.firstname = firstname;
  this.lastname = lastname;
  this.year = year;
}
Person.prototype.getAge = function(){
 return 2018 - this.year;
}
const april = new Person('April','kang', 1984)
const john = Object.create(Person.prototype);
console.log(april)
console.log(john)
