// Unable to understand what is wrong in this code always showing string is not // palindrome

const isPalindrome = (str) => {
  const str2 = str.split("").reverse().join("");

  if (str == str2) {
    console.log("It is a palindrome");
  } else {
    console.log("It is not a palindrome");
  }
};

isPalindrome('aabb');
isPalindrome('abba');

You can try this,

function palindrome(str) {
  let reversed = str.split('').reduce((acc, cur) => cur   acc, '');
  if (str === reversed) {
    return true;
  } else {
    return false;
  }
}
let str = "abba";
console.log(palindrome(str));
