Tell us what’s happening:

Idk what is wrong, each test is returning the right thing but for some reason it isn’t registering as correct.
EDIT: its because i changed the name of the functionFacepalm
Your code so far

{
    var array=[];
    str=str.toLowerCase();
    str=str.replace(/[\W_]+/g,"");
    var ogstr=str;
    array=str.split("");  
    array.reverse();
    str=array.join("");
    if (str==ogstr)
    {
        return true;
    }else{
        return false;
    }

}
