Is this the correct way for class inheritance within Javascript?

Question

Can someone confirm if the bellow script is indeed the correct way for class inheritance within Javascript?

WRONG WAY

var Person = function () {
   this.className = this.constructor.toString().match(/^function ([a-z_0-9]+)\(/i)[1];
   console.log( this.className ); //ERROR
}

var Mark = function () {
   Person.call(this);
}

Mark.prototype             = Object.create( Person.prototype );
Mark.prototype.constructor = Mark;

new Person; // I LIKE TO DISPLAY 'Person'
new Mark; // I LIKE DISPLAY 'Mark'

CORRECT WAY

function Person () {
   this.className = this.constructor.toString().match(/^function ([a-z_0-9]+)\(/i)[1];
   console.log( this.className );
}

function Mark () {
   Person.call(this); // Class Mark extend Person
}

Mark.prototype             = Object.create( Person.prototype );
Mark.prototype.constructor = Mark;

function Matteo () {
    Mark.call(this); // Class Matteo extend Mark
}

Matteo.prototype             = Object.create( Mark.prototype );
Matteo.prototype.constructor = Matteo;

new Person; // Displays: 'Person'
new Mark; // Displays: 'Mark'
new Matteo; // Display: 'Matteo'

Answer 1

This works for me:

 function Person () { console.log(this.constructor.toString().match(/^function ([a-z_0-9]+)\\(/i)[1]); } function Mark () { Person.call(this); } function Matteo() { Mark.call(this); } new Person(); // "Person" new Mark(); // "Mark" new Matteo(); // "Matteo"
