Answer 1

The function continues after the return true statement

No, it doesn't continue. It seems so to you, because of the recursive call. By the way, its result must also be returned, i.e. instead it
should just be
Well, there is no more check for an empty string.

Answer 2

function checkPalindrome(inputString) {
  var p = inputString.split(''),
    ch = p.slice().reverse();
  return p.toString() == ch.toString();
  }

  console.log (
  checkPalindrome('abcvvcba'),
  checkPalindrome('abcvcba'),
  checkPalindrome('bcbaaaa'),
  checkPalindrome('aaa')
  );
