JavaScript Class System with Multiple Inheritance



Build Status npm version

Ring.js is a class system in JavaScript allowing multiple inheritance.

var Human = ring.create({
  talk: function() {
    return "hello";

var Spider = ring.create({
  climb: function() {
    return "climbing";

var SpiderMan = ring.create([Spider, Human], {
  talk: function() {
    return this.$super() + ", my name is Peter Parker";

var spiderman = new SpiderMan();

Its advantages:

  • Stop fighting against JavaScript prototype-based object oriented system. Use a class system like you would in Java, Python, or basically any well-known language.
  • Available in the browser or in node.js. Also works with require.js.
  • The inheritance system is inspired by Python, one of the best multiple inheritance system ever.
  • Provides compatibility with other JavaScript class systems, like CoffeeScript or Backbone.
  • Licensed under the MIT license.
  • Damn, multiple inheritance just rocks!
