Package Exports
- class-extend
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (class-extend) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Class.extend 
Backbone's .extend like inheritance helper for Node.js
Usage
var Base = require('base');
// Extend from the blank class
var Sub = Base.extend();
// Add the .extend helper to a class
MyClass.extend = Base.extend;.extend()
.extend allow you to assign prototype and static methods.
If no constructor method is assigned, the parent constructor method will be called by default.
// Extend a class
var Sub = Parent.extend({
// Overwrite the default constructor
constructor: function () {},
// Sub class prototypes methods
hello: function () { console.log('hello'); }
}, {
// Constructor static methods
hey: function () { console.log('hey'); }
});
Sub.hey();
// LOG: hey
var instance = new Sub();
instance.hello();
// LOG: hello.__super__
Sub classes are assigned a __super__ static property pointing to their parent prototype.
var Sub = Parent.extend();
assert(Sub.__super__ === Parent.prototype);License
