Preparation HTML

<script>
var ns = (function(ns){

  ns.obj = {
   _x: 0
  }
  
  function Class() {
    this.x = 0
  }

  function Proto() {
    this.x = 0
  }
  Proto.prototype.get = function(){
    return this.x;
  };
  Proto.prototype.set = function(val){
    this.x = val;
  };

  function ProtoDefineInner() {
        var _x = 0
    Object.defineProperty(this, 'x', {
                get: function () { return _x },
                set: function (val) { _x = val }
        }) 
  }

ns.p = new ProtoDefineInner()
ns.p1 = new Class();
ns.p2 = new Proto();

return ns;
