Proxy
```
var p = new Proxy({}, {
get: function(target, prop, receiver) {
return 10;
}
});
var result = 0;
for (var i =0; i< 100000; i++){
result = result + p.a;
}
console.log(result);
```
```
var p = {};
Object.defineProperty(p, 'a', { get: function(x) { return 10; } });
var result = 0;
for (var i = 0; i< 100000; i++){
result = result + p.a;
}
console.log(result);
```
