I have been trying this question for a while, I am not sure what is wrong with my code.  
Odd number array with return true could not passed…

Shall I just go for split. reverse. join function then compare the two strings, instead of comparing arrays…

```javascript
function palindrome(str) {
  // Good luck!

  str = str.replace(/[^a-zA-Z 0-9]+/g,'');
  str = str.toLowerCase();
  
  var arrNum = str.length;
  // make it int not flort
  var middlePoint = Math.floor (arrNum /2);
  var j = 0;

  
  while( j < middlePoint) 
  {  
    if (str [j] == str [arrNum -1 - j])
    {
          j++;
          
          //if array is odd number
          if (j == (arrNum -1-j))
           {
               return true;
           }
     } 
     else 
     {
         return false;
     }       
  }
  return true;

}

```

I cleaned up your code.  
You need to use triple backticks to post code to the forum.  
See [this post for details](http://forum.freecodecamp.com/t/forum-code-formatting/25574).
