JavaScript Inheritance

constructor.js

// Constructors in prototypes

var Person = function(name) {
 this.name =  name;
}

var Student = function(name, university) {
  // this.name = name        // Wrong, no resusability;
  // Person(name)            // Wrong reference to this
  Student.call(this, name);
  this.university = university;
}

// Create a Student.prototype object that inherits from Person.prototype.
Student.prototype = Object.create(Person.prototype);

// Set the "constructor" property to refer to Student
Student.prototype.constructor = Student;
