Array.prototype.toReversed() — empty array

📖 Usage Example

const arr = []
arr.toReversed()  // → []

toReversed() on an empty array returns a new empty array.

Array.prototype.toReversed() — edge case: empty array

Calling toReversed() on an empty array returns a new empty array. There are no elements to reverse, so the result is simply [].

Challenge: Implement toReversedEmpty() that returns ([] as number[]).toReversed().

toReversedEmpty() // → []
