Bitovi

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 {Set}:
A set.
b {Set}:
A set.

Returns

{Set|Boolean}:

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

If EMPTY is returned, that means there is no difference or the sets are not comparable.
If UNDEFINABLE is returned, that means that B is a subset of A, but no set object can be returned that represents that set.
If UNKNOWABLE is returned, that means a result is unable to be determined.
