* Partitions `array` into a tuple of two arrays,
* where one array contains all elements that satisfies `predicate`,
* and the other contains all elements that do not satisfy `predicate`.
* @param array The array to partition. This array is not mutated.
* @param predicate The predicate function to determine in which partition the item should be placed.
* The function should return true for items that should be placed in the first partition, and false for those that should be placed in the second partition.
* @returns A tuple of two arrays.
