Package: effect
Module: Array

Array.setLastNonEmpty

Replaces the last element of a non-empty array with a new value.

When to use

Use when you already know the array is non-empty and the replacement value does not depend on the current last element.

Example (Setting the last element)

import { Array } from "effect"

console.log(Array.setLastNonEmpty([1, 2, 3], 4)) // [1, 2, 4]

See

• modifyLastNonEmpty — transform the last element with a function
• setHeadNonEmpty — replace the first element

Signature

declare const setLastNonEmpty: { <B>(b: B): <A>(self: NonEmptyReadonlyArray<A>) => NonEmptyArray<A | B>; <A, B>(self: NonEmptyReadonlyArray<A>, b: B): NonEmptyArray<A | B>; }
