Benchmark: Test Set versus Array-like object perfomance to get value

Script Preparation code:

var iSet = new Set();
var arr = [];
arr.byNum = {};

for (var i = 0;i++;i<500) {
    if (!arr.byNum[i]) {
      arr.push(i);
      arr.byNum[i] = i;
    }
  	iSet.add(i);
}

Tests:

Array Object
for (var i = 0;i++;i<500) { let a = arr.byNum[i] }
Set
for (var i = 0;i++;i<500) { let a = iSet.get(i) }
