setsubtract Function

The setsubtract function returns a new set containing the elements from the first set that are not present in the second set. In other words, it computes the relative complement (opens in a new tab) of the second set.

setsubtract(a, b)

Examples

> setsubtract(["a", "b", "c"], ["a", "c"])
toset([
  "b",
])

Set Difference (Symmetric Difference)

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