let s0 = new SndSet(v);
v = [3, 14, 14, 5, 9, 17];
let s1 = new SndSet(v);
let s2 = Array.from(SndSet.union(s0, s1));
console.log(s2);
// [2, 4, 5, 17, 'lulu', 3, 14, 9]

Intersection

let v = [2, 4, 4, 5, 17, "lulu"];
let s0 = new SndSet(v);

Difference

let v = [2, 4, 4, 5, 17, "lulu"];
let s0 = new SndSet(v);
v = [3, 14, 14, 5, 9, 17];
let s1 = new SndSet(v);
let s4 = Array.from(SndSet.diff(s0, s1));
console.log(s4);
// [2, 4, 'lulu']

Symmetric difference
