JavaScript Object-Oriented JavaScript (2015) Constructor Functions and Prototypes Creating Multiple Instances with Constructors

What if I don't want the instance to have all properties of the prototype?

Hi,

I was just wondering how can I create an instance of an object but without having all properties of the prototype:

function Person (name, job) { this.name = name; this.job = job; }

var Person2 = new Person ("Alina");

console // Person {name: "Alina", job: undefined}

I don't want the job property.

Thanks, Alina

You need a different constructor.

By definition, objects of the same type must have the same properties. So in this case, you need a different constructor for your new object type that only establishes the properties you want to have.
