 * `reduce(array, initial, reducer)`
 *
 * Reduces `array` to a single value by executing the `reducer` function on each element, starting with the `initial` accumulator value.
 *
 * ```ts
 * reduce([1, 2, 3, 4], 0, (acc, x) => acc + x); // 10
 * ```
 *
 * ```ts
 * pipe(
 *     [1, 2, 3, 4],
 *     reduce(0, (acc, x) => acc + x),
 * ); // 10
 * ```
