Variable access using JavaScript OO

Based on Java coding:

public Class Dog {
    int a = 1;;
    int b = this.a;
    public int c() {
        return a+b;

Corresponding with JavaScript, we have:

function Dog() {
    d = new Object();
    d.a = 1;
    d.b = d.a;
    d.c = function() {
        return this.a+this.b;
    return d;

Remember in JavaScript, if variable b want to get variable a, should use d.a but not this.a, however inside method, want to get variable a, should use this.a instead of d.a.

This is a kind of JavaScript Object-oriented reliazation method.
