in ECMAScript 6, supposedly, but until then I need a class factory that fills the gap.
For me that means (in no particular order):
- prototypal inheritance under the hood
- access to overridden properties (
- inheritance of

- ES5/browser compatibility
- only-pay-for-what-you-use performance

npm install cls
cd path/to/node_modules git clone git://github.com/benjamn/cls.git cd cls npm install .
One example will have to suffice for now:
var cls = ;var BaseClass = cls;var SubClass = BaseClass;;;;;;;;
