Well, just "works", but not so nice, imho, is this:

var foo = { 
   'name':'bar', 
   'width':600, 
   get height(){return this.width * 2;} 
};
alert(foo.height); // 1200
foo.height = 7; 
// Uncaught TypeError: Cannot set property height of #<Object> 
// which has only a getter

==========

and also not so nice, imho, is:

var vvv;
var foo = { 
   get height(){return vvv * 2;} 
}; 
alert(foo.height) ; // NaN
vvv = 20;
alert(foo.height) ; // 40
vvv = 7;
alert(foo.height) ; // 14

==========
