dejavu

By default JavaScript supports prototype inheritance.

dejavu adds support for class inheritance, the essential feature needed to support object-oriented programming (OOP), the base of all large scale applications in any programming language.

dejavu doesn't destroy prototype inheritance, building class inheritance on top of it, allowing older JavaScript code to still work without crashing the app.
