Tell us what’s happening:
palindrome(“1 eye for of 1 eye.”) should return false.
why it should ???
You’ll need to !!!remove!!! all non-alphanumeric characters (punctuation, !!!spaces!!! and symbols) and turn everything into the same case (lower or upper case) in order to check for palindromes.

Your code so far


function palindrome(str) {
    let filtred = str.toLowerCase().split('').filter(a=>a.charCodeAt(0)>96&&a.charCodeAt(0)<123).join('');
    console.log(filtred);
    return filtred.split('').reverse().join('') == filtred;
}



palindrome("eye");
