Script Preparation code:

var map = new Map([[1, 1]]);
var obj = {1: 1};
var count = 100; 
var a, i;


for (let j = 0; j < count; j++) {
  map.set(j, j);
  obj[j] = j;
}

var map = new Map([[1, 1]]);var obj = {1: 1};var count = 100; var a, i;​​for (let j = 0; j < count; j++) {  map.set(j, j);  obj[j] = j;}

Tests:

for (i = 0; i < count; i++) {
  a = obj[i];
}

 
for (i = 0; i < count; i++) {  a = obj[i];}

for (i = 0; i < count; i++) {
  a = map.get(i);
}

 
for (i = 0; i < count; i++) {  a = map.get(i);}

for (i = 0; i < count; i++) {
  a = map.has(i)
}

 
for (i = 0; i < count; i++) {  a = map.has(i)}
