//Steps to think through..

// 1. we need to remove unneeded whitespace/numbers and whitespace. Needs to be lower case.
// 2. Need to then create another variable with the string turned into an array and reverse joined. 
// 3. Compare the two created strings to see if they match. return F/A statement.


function palindrome(str) {
  // Good luck!
  
  var replaceAndLower =str.replace(/[^A-Z0-9]/ig, "").toLowerCase();
  var reversedStr = replaceAndLower.split('').reverse().join('');
  
  if (reversedStr === replaceAndLower) {
    return true;
  } else {
    return false;
  }
}



palindrome("eye");
