If (((_ok)? true: (Math.random() 0.1))) {return res;}

  • The code in question is:

                } catch (Exception e) {
                    if (!((_ok) ? true : (Math.random() > 0.1))) {
                        return res;
                    }
                    (error logging)
                    _ok = false;
                }
    
    A 10% percent chance to skip logging under certain circumstances. Very strange code, and a strange way to write it. Also wouldn't this be equivalent to

        if (!_ok || (Math.random() > 0.1))
