Silly, it come from me, as you clearly quote!

An absolute "the best one"???????????? [see below]

I agree, it was the best iyho, but not in imho.

var foo {  "name":"bar", "width":600 };
foo.height = foo.width * 2;

... makes results in what is real usefull,
as it does not suffer from the error possibillity,
if someone later wants to change foo.height.

if foo.height is just a 'getter', a later:

foo.height = foo.width * 3;

using 'getter' would throw unexpectedly:

>// Uncaught TypeError: Cannot set property height of #<Object> 
>// which has only a getter

which imho does not getter better.

The 'getter' method is nice and usefull, 
but less simple and more error-prone,
as most shortcut codes are.

Mixing 'getters' with ordinary object properties,
would perhaps need a naming-convention that alerts the unwary,
like:

var foo = { 
   'nameProperty':'bar', 
   'widthProperty':600, 
   get heightGetter(){return this.width * 2;} 
};

Thomas c/should come up with a better naming-convention.
