Add Items to an Array with push() and unshift() with spread op

Tell us what’s happening:

I am using the spread operator here with the push and unshift method and the return is: [“I”, 2, “three”, “IV”, 5, “six”, 7, “VIII”, 9].

But somehow I can’t pass the “utilize the push() method” & “utilize the unshift() method”.

Your code so far


function mixedNumbers(arr) {
  // change code below this line
    let front = ['I', 2, 'three'];
    let end = [7, 'VIII', 9];
    arr.unshift(...front);
    arr.push(...end);
  // change code above this line
  return arr;
}

// do not change code below this line
console.log(mixedNumbers(['IV', 5, 'six']));

It looks like the tests won’t recognize the use of these methods with a spread operator. If you like, you can create a GitHub Issue to suggest that the tests be updated. Whenever reporting a bug, please check first that there isn’t already an issue for it and provide as much detail as possible.
