assertArrayLength

assertArrayLength

Assert that an array has exactly the expected length, with type narrowing.

The type narrowing indicates: - An empty array for 0 - An exact number of elements up to 10 - At least 10 elements for >10

Usage

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

const value: unknown = ["admin", "editor"];

assertArrayLength(value, 2);

// value is now narrowed to an array with exactly 2 elements
