Benchmark: globals vs. upvalues

HTML Preparation code:

<script>
'use strict';

const l = (function() {
  'use strict';
  const localObj = {x : 0};
  return function() {
    ++localObj.x;
  };
})();

Function(`return this`)().globalObj = {x : 0};

const g = function() {
  'use strict';
  ++globalObj.x;
};

Object.defineProperty(
	Function(`return this`)(),
	`globalObj2`,
	{value : {x : 0}, __proto__ : null,});

const g2 = function() {
  'use strict';
  ++globalObj2.x;
};
  
</script>
