Review first project in js Palindrome Checker?

Tell us what’s happening:
Is there a better shortcode than this?

  **Your code so far**

function palindrome(str) {

str = str.toLowerCase().replace(/[\W_]/g, '');
for(var i = 0, len = str.length - 1; i < len/2; i++) {
  if(str[i] !== str[len-i]) {
    return false;
return true;

console.log(palindrome("0_0 (: /-\ :) 0-0"));
