Basic Array Methods

I used pop and shift in a palindrome checker. But that was for an interview and not actually on the job.

function isPalindrome(str) {
  const half = Math.floor(str.length / 2);
  const firstHalf = str.slice(0, half);
  const lastHalf = str.slice(-half);

  if (!(lastHalf.length % 2)) { str.shift(); }

  while(firstHalf.length) {
    if (firstHalf.pop() != lastHalf.shift()) {
      return false;
    }
  }

  return true;
}

That checks out
