/**
 * `findMapLastOrElse(array, predicate, mapper, callback)`
 *
 * Finds the last element in `array` that satisfies the provided `predicate` function and applies the `mapper` function to it, returning a new array with the mapped element, or the result of calling `callback` with the array if no element is found.
 *
 * ```ts
 * findMapLastOrElse(
 *     [1, 2, 3, 4],
 *     (x) => x > 10,
 *     (x) => x * 10,
 *     (arr) => arr.length,
 * ); // 4
 * ```
 *
 * ```ts
 * pipe(
 *     [1, 2, 3, 4],
 *     findMapLastOrElse(
 *         (x) => x > 10,
 *         (x) => x * 10,
 *         (arr) => arr.length,
 *     ),
 * ); // 4
 * ```
