var fun = function(i) {
	return i;
};

var evalCode = 'i;';

Object.defineProperty(window, 'getterBenchmark', {
	get value() {
		return 'hi';
	}
});

Function
for(let i = 0; i < 5; i++) { fun(i); };
Eval
for(let i = 0; i < 5; i++) { eval(evalCode); };
Getter
for(let i = 0; i < 5; i++) { getterBenchmark; };
