 * ```ts

 *
 * Returns the mean (average) value from `array`, or throws an error if the array is empty.
 *
 * ## Example
 *
 * ```ts [data-first]
 * import { Array } from "@monstermann/array";
 *
 * Array.meanOrThrow([1, 2, 3]); // 2
 * Array.meanOrThrow([]); // throws FnError
 * ```
 *
 * ```ts [data-last]
 * import { Array } from "@monstermann/array";
 *
 * pipe([1, 2, 3], Array.meanOrThrow()); // 2
 * pipe([], Array.meanOrThrow()); // throws FnError
 * ```
