ain't this way the same thing as using ( class, constructor )

function Person(firstName,lastName,age,eyeColor) {
  this.firstName = firstName;
  this.lastName = lastName;
  this.age = age;
  this.eyeColor = eyeColor;
  this.changeName = function (name) {
    this.lastName = name;
  }
}

var myMother = new Person("Sally","Rally",48,"green");

At heart, JavaScript is a prototype-based language, and this is an example of the conventional approach to creating an object.

The new "class" syntax just gives you a new way to do the same things but in a way that appears more similar to a truly class-based language.

So you're right, the object you create with either syntax is essentially the same.
