A utility library for TypeScript.

import { OrElse } from "./internals/types.js";

//#region src/array/replaceLastOrElse.d.ts

/**
 * `replaceLastOrElse(target, value, replacement, orElse)`
 *
 * Replaces the last occurrence of `value` in `target` with `replacement`. If `value` is not found, calls `orElse` with the original array.
 *
 * ```ts
 * replaceLastOrElse([1, 2, 3, 2], 2, 9, () => []); // [1, 2, 3, 9]
 * replaceLastOrElse([1, 2, 3], 4, 9, (arr) => arr); // [1, 2, 3]
 * ```
 *
 * ```ts
 * pipe(
 *     [1, 2, 3, 2],
 *     replaceLastOrElse(2, 9, () => []),
 * ); // [1, 2, 3, 9]
 * pipe(
 *     [1, 2, 3],
 *     replaceLastOrElse(4, 9, (arr) => arr),
 * ); // [1, 2, 3]
 * ```
