Another ways to create object using Object.create()

 showing object creating using Object.create() using the following example,

var personProto={

    calculateAge:function(){

        console.log(2021-this.yearOfBirth);

    }

}

var john = Object.create(personProto);

john.name="john smith";

john.yearOfBirth=1989;

john.job = "engineer";

console.log(john);

john.calculateAge();

here ,personProto is a prototype which i am using to create an object,

var john = Object.create(personProto);

we first create john object then we define properties.

Another way to create an object-

var john = Object.create(personProto, {

    name: {

        value: "john"

    },

    yearOfBirth: {

        value: 1989

    },

    job: {

        value: "engineer"

    }

});

john.calculateAge();

the difference with function constructor is that , we inherit the property when we creating the object .
