```lua

    Write a function that checks if a number is even or odd.
    The function should:
    - Take a single number parameter
    - Return "even" for even numbers
    - Return "odd" for odd numbers
    - Handle negative numbers as well

    Example:
    isEvenOrOdd(4) should return "even"
    isEvenOrOdd(3) should return "odd"
    isEvenOrOdd(-2) should return "even"
    isEvenOrOdd(-3) should return "odd"
    ]]

    local testCases = {
        { input = {4}, expected = "even" },
        { input = {3}, expected = "odd" },
        { input = {-2}, expected = "even" },
        { input = {-3}, expected = "odd" }
    }

    -- Expected Response
