##Tricks

###Inheritance

```javascript

'use strict';

//Classic OOP

var Rectangle = function (length, width) {

  this.length = length;

  this.width  = width;

  //Methods defined internally

  this.calcArea = function() {

      return this.length * this.width;

  };

};

var Square =  function (length) {

  this.length = length;

  this.width  = length;

};

//For Inheriting all methods

Square.prototype =  new Rectangle();

//OR

Square.prototype =  Object.create(Rectangle.prototype);

//Creating instance of Square

var mySquare = new Square(2);

console.log(mySquare.calcArea());

//Result:

4

//Modular Inheritance

//Base.js

function Base() {}

Base.prototype.print = function() {

  Console.log('Printing.');

};

module.exports = Base;

//User.js

var util = require('util');

var Base = require('relative/or/absolute/path/to/Base');

function User() {}

util.inherits(User, Base);

module.exports = User;

User.prototype.display = function() {

  Console.log('Displaying.');

};

var User    = require('relative/or/absolute/path/to/User');

var userObj = new User();

userObj.print();   //Printing.

userObj.display();   //Displaying.'

```
