I have a situation where I instantiate a base class, but later may need to
update the prototype once I gain more information.
*var Animal = new Class({});*
*var Cow = new Class({*
* Extends: Animal*
*});*
*var something = new Animal();*
If I later find out that something is a Cow, how can I change it to be so?
I know the once frowned upon method of setting __proto__ works in non-IE,
but is there another way, or through MooTools? I only need IE9+ support.
*something.__proto__ = Cow.prototype;*
*if(something instanceof Cow)*
* alert('moo');*
Thanks!
