  // Only change code below this line
newArr += [[...arr]];

  num--;
}

return newArr;

Hey @CodebanK!

It’s interesting because you wrote a comment that is actually the answer but then you didn’t apply it to your actual code. So I would see if I could use that comment to my advantage.

Hope that helps!
