Function areSetsDisjoint

Checks if two sets are disjoint; that is, if both sets have no elements in common.

• Formal definition: A ∩ B = ϕ
• This method runs in bilinear time, or O(m * n), where m = |B| (size of set B) and n = |A| (size of set A).

Example

// {1, 2, 3} ∩ {4, 5, 6} = ϕ
areSetsDisjoint(new Set([1, 2, 3]), new Set([4, 5, 6])); // true

// {1, 2, 3} ∩ {3, 4, 5} ≠ ϕ
areSetsDisjoint(new Set([1, 2, 3]), new Set([3, 4, 5])); // false
