Tell us what’s happening:

I am not certain why this is not passing the challenge. It all checks out to me!

Your code so far


function popShift(arr) {

popShift.pop(); // change this line
popShift.shift(); // change this line

  return [shifted, popped];
}

// do not change code below this line
console.log(popShift(['challenge', 'is', 'not', 'complete']));
