/**
 * # mapAtOr
 *
 * ```ts
 * function Array.mapAtOr<T, U>(
 *     target: readonly T[],
 *     idx: number,
 *     map: (
 *         value: NoInfer<T>,
 *         index: number,
 *         target: readonly NoInfer<T>[],
 *     ) => T,
 *     or: U,
 * ): readonly T[] | U
 * ```
 *
 * Applies the `mapper` function to the element at the specified `index` in `array`, returning a new array with the mapped element, or `fallback` if the index is out of bounds.
 *
 * ## Example
 *
 * ```ts [data-first]
 * import { Array } from "@monstermann/array";
 *
 * Array.mapAtOr([1, 2, 3], 10, (x) => x * 10, []); // []
 * ```
 *
 * ```ts [data-last]
 * import { Array } from "@monstermann/array";
 *
 * pipe(
 *     [1, 2, 3],
 *     Array.mapAtOr(10, (x) => x * 10, []),
 * ); // []
 * ```
