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:

Map 1
let b; for (i = 0; i < count; i++) { a = map.get(i); if (a) { b = a; } }
Map 2
let b; for (i = 0; i < count; i++) { if (map.has(i)) { b = map.get(i); } }
