Please describe how to reproduce this issue, and include links to screenshots if possible.

My code:
```javascript
function palindrome(str) {
var z;
str = str.toLowerCase();
console.log(str);
s = str.replace(/[\s|\,|\.]/g,"").test();
var d = s.split("");
var a = d.reverse();
var b = a.join("");
if(s != b){
return false;
}
return true;
}
palindrome("0_0 (: /-\ :) 0-0");
```
