setUnion

Try it yourself:

@1	setUnion([1, 2, 3, 4], [3, 4, 5, 6])
@2	setUnion([[1, 2], [3, 4]], [[3, 4], [5, 6]])

Combine set members with setUnion

setUnion(A, B) returns every distinct member found in either set. It is the natural operation for merging tags, permissions, or candidate lists.

The union of {1,2} and {2,3} is {1,2,3}. Use setIntersect for only common members and setSymDifference for only non-shared members.

Union removes duplicate membership. Use concat when duplicates and source order must remain, and setSize to count the merged distinct result.
