var i = 0, count = 1000, a;
var map = new Map();

for (i = 0; i < count; i++) {
  if (Math.random() > 0.5) {
    map.set(i, i * i);

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

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

Map 2

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

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