setunion Function

The setunion function takes multiple sets and produces a single set containing the elements from all of the given sets. In other words, it computes the union (opens in a new tab) of the sets.



> setunion(["a", "b"], ["b", "c"], ["d"])

The given arguments are converted to sets, so the result is also a set and the ordering of the given elements is not preserved.
