 * A function which returns the next or previous date for a specific week day. For example, `Day.Monday`.
 *
 * @param date - The date to calculate from.
 * @param weekDay - The `Day` enum specifying the desired week day.
 * @param direction - The `Direction` enum specifying the calculation direction.
 * @returns - A `Date` instance.

 * ```ts-no-run
 * dayOfWeek(new Date(2016, 0, 1), Day.Wednesday, Direction.Forward); // 2016-01-06, Wednesday
 * dayOfWeek(new Date(2016, 0, 1), Day.Wednesday, Direction.Backward); // 2015-12-30, Wednesday
