assertArrayEmpty

Assert that an array has no elements, with type-narrowing.

The failure message names the elements that are present, which is usually the diagnostic the assertion exists to produce.

Usage

import { assertArrayEmpty } from "@kensio/smartass";

const value: unknown = [];

assertArrayEmpty(value);

// value is now narrowed to an empty array
