/*
Add Items to an Array with push() and unshift():
We have defined a function, mixedNumbers, which we are passing an array as an argument.
Modify the function by using push() and unshift() to add 'I', 2, 'three' to the beginning of the array and 7, 'VIII', 9
to the end so that the returned array contains representations of the numbers 1-9 in order.

- mixedNumbers(["IV", 5, "six"]) should now return ["I", 2, "three", "IV", 5, "six", 7, "VIII", 9]
- The mixedNumbers function should utilize the push() method
- The mixedNumbers function should utilize the unshift() method
 */
function mixedNumbers(arr) {
    // Only changed code below this line
    arr.unshift("I", 2, "three")
    arr.push(7, "VIII", 9)
    // Only changed code above this line
    return arr;
}

console.log(mixedNumbers(['IV', 5, 'six']));
