Palindrome

Directions

Given a string, return true if the string is a palindrome or false if it is not.

Palindromes are strings that form the same word if it is reversed. *Do* include spaces and punctuation in determining if the string is a palindrome.

Examples:

palindrome("abba") === true

palindrome("abcdefg") === false

    function palindrome(str) {
      if (!str) {
          return str;
      }
    
      for (let i = 0; i < str.length/2 + 1; i++) {
          if (str[i] !== str[str.length-i-1]) {
              return false;
          }
      }
      return true;
