Set.prototype.values()

values() method는 Set 객체에 요소가 삽입된 순서대로 각 요소의 값을 순환할 수 있는 Iterator 객체를 반환합니다.

The keys() method is an alias for this method (for similarity with Map objects); it behaves exactly the same and returns values of Set elements.

mySet.values();

A new Iterator object containing the values for each element in the given Set, in insertion order.

var mySet = new Set();
mySet.add('foo');
mySet.add('bar');
mySet.add('baz');

var setIter = mySet.values();

console.log(setIter.next().value); // "foo"
console.log(setIter.next().value); // "bar"
console.log(setIter.next().value); // "baz"
