since the logic within `getIntersection` depends on the values being sorted correctly (`arrayA[ai] < arrayB[bi]`) and .sort is not stable and even gives a wrong result according to decimal computation( [14,2].sort() = [14,2], so we must at least give the `compareFunction` for simple cases (which fits to our needs, as we compare Ids).
