                                        var output = arr[0];
    
                                        for(var i = 1; i < arr.length; i++) {
                                                output += arr[i].charAt(0).toUpperCase() + arr[i].slice(1, arr[i].length);

    }

        return memo + token.slice(0, 1).toUpperCase() + token.slice(1);
      });
