Benchmark: Set.difference vs Filter + includes

Script Preparation code:

const array1 = Array.from({length: 100}, () => Math.floor(Math.random() * 140));
const array2 = Array.from({length: 100}, () => Math.floor(Math.random() * 140));

Tests:

Sets
const set1 = new Set(array1); const set2 = new Set(array2); set1.difference(set2);
Arrays
array1.filter((id) => !array2.includes(id));
