i.g:

function Constructor(input){
     this.input = input;
}

Object.__defineGetter__.call(Constructor.prototype, "value", function(){
    return this.input * 2;
});

Object.__defineSetter__.call(Constructor.prototype, "bar", function(foo){
    return this.input *= foo;
});

var test = new Constructor(5);
console.log(test.value); // 10
test.bar = 5;
console.log(test.input); //25

With that said, this feature is deprecated, advices to not to use in production coding.
