Module: Array

Array.dedupeAdjacentWith

Removes consecutive duplicate elements using a custom equivalence.

When to use

Use when consecutive duplicates should be collapsed using a custom equivalence, while equivalent values that appear later should remain in the result.

Details

Non-adjacent duplicates are preserved.

Example (Deduplicating adjacent elements)

import { Array } from "effect"

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

See

• dedupeAdjacent — uses default equality
• dedupeWith — dedupes all duplicates, not just adjacent

Signature

declare const dedupeAdjacentWith: { <A>(isEquivalent: (self: A, that: A) => boolean): (self: Iterable<A>) => Array<A>; <A>(self: Iterable<A>, isEquivalent: (self: A, that: A) => boolean): Array<A>; }
