Function getDifference

Represents the difference set operation, where the difference is the set of elements in set B that are not in set A.

• Formal definition: B \ A = {x: x ∈ B | x ∉ A}
• This method runs in linear time, or O(n), where n = |B| (size of set B).
• This method has no side effects, returning a new Set<TElement> instance.

Set.prototype.difference

Example

//{1, 2, 3} \ {3, 5} = {1, 2}
getDifference(new Set([1, 2, 3]), new Set([3, 5])); // new Set([1, 2])
