How to extend the Javascript Date object?

Question

I\'m trying to subclass/extend the native Date object, without modifying the native object itself.

I\'ve tried this:

    var util = require(\'util\')         


        

Answer 1

In ES6, it will be possible to subclass built-in constructors (Array, Date, and Error) - reference

Problem is there is no way to do this with current ES5 engines, as Babel indicates and will require a browser with native ES6 support.

The current ES6 browser support for subclassing is pretty weak / non-existant as of today (2015-04-15).
