Package: effect
Module: Array

Array.containsWith

Returns a membership-test function using a custom equivalence.

When to use

Use when checking membership with caller-provided equality instead of Equal.equivalence().

Example (Checking with custom equality)

import { Array, pipe } from "effect"

const containsNumber = Array.containsWith((a: number, b: number) => a === b)
console.log(pipe([1, 2, 3, 4], containsNumber(3))) // true

See

• contains for the Equal.equivalence() variant

Signature

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