Calculates the union of two arrays using the provided equivalence relation.

Signature

declare const unionWith: { <S extends Iterable<any>, T extends Iterable<any>>(that: T, isEquivalent: (self: ReadonlyArray.Infer<S>, that: ReadonlyArray.Infer<T>) => boolean): (self: S) => ReadonlyArray.OrNonEmpty<S, T, ReadonlyArray.Infer<S> | ReadonlyArray.Infer<T>>; <A, B>(self: NonEmptyReadonlyArray<A>, that: Iterable<B>, isEquivalent: (self: A, that: B) => boolean): NonEmptyArray<A | B>; <A, B>(self: Iterable<A>, that: NonEmptyReadonlyArray<B>, isEquivalent: (self: A, that: B) => boolean): NonEmptyArray<A | B>; <A, B>(self: Iterable<A>, that: Iterable<B>, isEquivalent: (self: A, that: B) => boolean): Array<A | B>; }
