Lisn.js - zero-dependency Backbone.js Events implementation

Reason why I've created clone of Backbone.js Events is that fact what Backbone.js (1) depends on Underscore.js and (2) it backed in one solid file. There is no way to reuse Backbone.js components separetly.

Lisn.js created for give power and simplicity of Backbone.js Events to another libraries and lightweight web pages (e.g mobile or landing).

Key features

Lisn.js is fully compatible with original Backbone.js's API,
it designed to be as light as possible,
Lisn.js doesn't depends on 3rd-party libraries,
it works on all modern browsers (IE>=9),
it written in CoffeeScript but can be used as vanilla JS.

Description

TODO

Usage

Extend your object with Lisn to give it ability to bind and trigger custom events.

How to extend your object with Lisn?

Vanilla JavaScript:

for (var property in Lisn) {
  yourObject[property] = Lisn[property];
}

CoffeeScript:

yourObject[property] = fn for property, fn of Lisn

Underscore.js:

_.extend(yourObject, Lisn);

Sugar.js:

Object.merge(yourObject, Lisn);

Easy, right?

Basic example

yourObject.on('bat-signal', function () {
  alert('(>v^v<)');
});

yourObject.trigger('bat-signal');

Try to guess what is result of this snippet? Yes, right. In your door will knock Batman.

API
