node. JS Inheritance

Person.js

Module.exports = function () {
THIS.name = "Person";
This.sleep = function () {
Console.log ("Sleep in the Night");
}
This.eat = function () {
Console.log (' eat food ');
}
}

Student.js

var util = require ("util");
var person = require ('./person ');

Defining the Student Class
function Student () {
Person.call (this);
}

Inherit student to Person
Util.inherits (Student,person);

Overriding the study method
Student.prototype.study = function () {
Console.log ("I am Learning");
}

Exposed Student class
Module.exports = Student;

Testinherits.js

var person = require ('./person ');
var Student = require ('./student ');

var personobj = new Person ();
var studentobj = new Student ();

Console.log ("-------for base class of person-------");
Personobj.sleep ();
Personobj.eat ();
Console.log ("---------------------------------");

Console.log ("-------for base class of student-------");
Studentobj.sleep ();
Studentobj.eat ();
Studentobj.study ();
Console.log ("---------------------------------");

Static call

var util = require ("util");
var person = require ('./person ');

Defining the Student Class
function Student () {
Person.call (this);
}

Inherit student to Person
Util.inherits (Student,person);

Overriding the study method
Student.prototype.study = function () {
Console.log ("I am Learning");
}

Exposing the method of the dynamic object directly to the Module.exports

var student= new student ();
Module.exports.study = Student.study;

Module.exports.eat = Student.eat;

Module.exports.sleep = Student.sleep;

Static call testing without instantiating the student object,

var Student = require ('./student ');

Student.sleep ();
Student.eat ();
Student.study ();
