Benchmark: Set Iteration with spread 2

HTML Preparation code:

<script>
window.object = {};
for (var i = 0, length = Math.pow(10, 5); i < length; ++i) object[i] = Math.random();
window.array = Object.getOwnPropertyNames(object).map(function(key) {
  return object[key];
});
try {
  window.set = new Set(array);
} catch(e){
  console.log("Set is not supported");
}
try {
  window.map = new Map(array.map(function(value, i) {
  return [i, value];
}));
} catch(e){
  console.log("Map is not supported");
}

//chrome bug
if (window.set && set.size == 0 || window.map && map.size == 0) array.forEach(function(value, index) {
  if (window.set) set.add(value);
  if (window.map) map.set(index, value);
});
window.method = function(value, index, container) {
  value;
  index;
  container;
}
</script>

Tests:

set foreach
set.forEach(method);
set spread
[...set].forEach(method);
set iterator
var iterator = set.values(); var iteratorResult = iterator.next(); while (!iteratorResult.done) { method() var iteratorResult = iterator.next(); }
