intersection

`algebra.intersection(a, b)`

Returns a set that represents the intersection of sets A and B (A ∩ B).

algebra.intersection(
  {completed: true, due: "tomorrow"},
  {completed: true, type: "critical"},
) //-> {completed: true, due: "tomorrow", type: "critical"}

Parameters

a {[}:
A set.
b {[}:
A set.

Returns

{Set|Boolean}:

If an object is returned, it represents the intersection of sets A and B (A ∩ B).

If true is returned, that means that an intersection exists, but no set object can be returned that represents that set.

If false is returned, that means there is intersection.
