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);

Tests:

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

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

let b;
for (i = 0; i < count; i++) {
  if (map.has(i)) {
    b = map.get(i);
  }
}

 
let b;for (i = 0; i < count; i++) {  if (map.has(i)) {    b = map.get(i);  }}
