  • Palindrome Challenge - Syntax correct, why is the output returning false?
    Hi, I am a newbie working on the easy challenges. I have been working on the Palindrome challenge. I have verified the syntax is correct, but the output is returning false regardless what input I use. I have gone through the code several times, and the order seems logical to me. I have looked at example codes, but they seem to take different approaches and I want to see if my code is workable for this solution. Any advice on where I am going wrong would be appreciated. Example:
    var str = "eye"
    str === reverseWord 
    
    should return true.
    function Palindrome(str) { 
    
     var reverseLetter = str.split('').reverse().join(''); 
     var reverseWord = null; 
    
      for (var i = 0; i < str.length; i++) {
           reverseWord += str[i]; 
      }
        if (str === reverseWord) {
          return true;
            } 
    
        else {
          return false;
        }
    }

  • Hey. Adding letters to null looks like the problem, change null to empty quotes.

  • Also, you declare the var reverseLetter but you never use it again to make any comparisons, by the looks of your code reverseWord is never changed, you just make a direct copy of str with another name.

  • There is no need for you to have one both reverseLetter and reverseWord. You have the reversed word in your reverseLetter line. After you have that, it is a simple comparitive to see if their the same here is a working version of your code
    function workingPalindrome(str){
    var reverseWord = str.split('').reverse().join('');
    if(str == reverseWord){
    return true
    }else{
    return false
    }
    }

  • Also you don't appear to be taking into accout spaces between your words/letters. You need to negate the spaces, too.
