Reverse Array
Return a new array with the elements in reverse order, without mutating the input.
Examples
- reverseArray([1, 2, 3]) → [3, 2, 1]
Constraints
- Keep the required function name so the tests can find it
- Return a value instead of only logging it
- Do not mutate inputs unless the challenge asks you to
