defineProperty
var obj = function() {};
Object.defineProperty(obj.prototype, 'width', {
  get: function() {
    return this.width;
  },
  set: function(w) {
    this.width = Number(w);
  }

Object.defineProperty(obj, 'height', {
  get: function() {
    return this.height;
  },
  set: function(h) {
    this.height = Number(h);
  }
});
ready
defineProperties
var obj = function() {};
Object.defineProperties(obj.prototype, {
  width: {
    get: function() {
      return this.width;
    },
    set: function(w) {
      this.width = Number(w);

getter
var obj = function() {};
obj.prototype = {
  get width() {
    return this.width;
  },
  set width(w) {
    this.width = Number(w);
  },
  get height() {

  set height(h) {
    this.height = Number(h);

ready
getter with eval
var obj = function() {};
obj.prototype = eval('({get width() {return this.width;},set width(w) {this.width = Number(w); },  get height() {return this.height; }, set height(h) { this.height = Number(h); }})');
