Package: effect
Module: Array

Array.dedupeWith

Removes duplicates using a custom equivalence, preserving the order of the first occurrence.

When to use

Use to remove all duplicate elements with a custom equivalence when default equality is not appropriate.

Example (Deduplicating with custom equality)

import { Array } from "effect"

console.log(Array.dedupeWith([1, 2, 2, 3, 3, 3], (a, b) => a === b)) // [1, 2, 3]

See

• dedupe — uses default equality
• dedupeAdjacentWith — only dedupes consecutive elements

Signature

declare const dedupeWith: { <S extends Iterable<any>>(isEquivalent: (self: ReadonlyArray.Infer<S>, that: ReadonlyArray.Infer<S>) => boolean): (self: S) => ReadonlyArray.With<S, ReadonlyArray.Infer<S>>; <A>(self: NonEmptyReadonlyArray<A>, isEquivalent: (self: A, that: A) => boolean): NonEmptyArray<A>; <A>(self: Iterable<A>, isEquivalent: (self: A, that: A) => boolean): Array<A>; }
