palindrome

palindrome for numbers and strings

function palindrome(str) {
if (!isNaN(str)) {  str = str.toString(); }
  var re = /[\W_]/g;
  var lowRegStr = str.toLowerCase().replace(re, '');
  var reverseStr = lowRegStr.split('').reverse().join(''); 
   
  return reverseStr === lowRegStr;
}
palindrome("11222211");



and my personal Palindrome ------------------------------------------------------ WORKSSSSSSSSSSSSSSSSSSSSSSSSSS

function palindrome(str) {
if (!isNaN(str)) {  
  str = str.parseInt(); 
} else if (isNaN(str)){
str = str.toString();
} 
 
  var reverseStr = str.split('').reverse().join('');
    
  return reverseStr === str;
}
palindrome("eye"); //or "11222211" or "121" or whatever
