Abitbol is a small Javascript library that provides consistent/easy to use classes for Node.js and web browsers. It is heavily inspired by Armin Ronacher's Classy library, but extends its possibilities.
  • Simple inheritance
  • Consistent this (always points to the current instance)
  • Annotations
  • Computed properties automatically generated from getters and setters
  • Simple way to call a super class method
  • Simple way to declare static properties
  • Handful mixin

Exemple class definition:
var Vehicle = Class.$extend({

    __init__: function(color) {
        this.color = color;
        this.speed = 0;

    move: function(speed) {
        this.speed = speed;

    stop: function() {
        this.speed = 0;
