The Javascript Set @@iterator property returns iterator.

Its initial value is the same function object as the initial value of the values property. 

mySet[Symbol.iterator]

const mySet = new Set();/*w ww  . j  ava2  s .c  om*/
mySet.add('0');
mySet.add(1);
mySet.add('1');
mySet.add({});

const setIter = mySet[Symbol.iterator]();

console.log(setIter.next().value); 
console.log(setIter.next().value); 
console.log(setIter.next().value); 
console.log(setIter.next().value);
