// Examples
const setA = new Set([1, 2, 3, 4]);
const setB = new Set([2, 3]);
const setC = new Set([3, 4, 5, 6]);

isSuperset(setA, setB); // returns true
union(setA, setC); // returns Set {1, 2, 3, 4, 5, 6}
intersection(setA, setC); // returns Set {3, 4}
symmetricDifference(setA, setC); // returns Set {1, 2, 5, 6}
difference(setA, setC); // returns Set {1, 2}

const language = {
  set current(name) {
    this.log.push(name);
  },
  log: []
};

language.current = 'EN';
language.current = 'FA';

console.log(language.log);
// expected output: Array ["EN", "FA"]
