How to detect an error in the condition c true false?

Question

JavaScript

Help identify the error in the condition. It should work when there are 12 characters in the input, but it only works when there are 11 characters, although 12 is indicated in the condition. If you put 12 and equal, then this part of the code does not work, which is strict (
here is the part of the code with the condition:

var phone = this.value;
                    if (!phone || phone.replace(/\D/g, '').length < 12) enable = false;
                    if (codes[phone.substr(5, 3)]) {
                        valid = true
                    } else if (enable == true & valid == false  ) {
                        $('.form-control').val('Некорректный ввод');
                    }
                    if (enable == false & valid == true) {
                        obj = {
                            dates: 'дата',
                            time: 'время',
                            phone: phone
                        };
                        obj['date'] = retite
                        alert(obj['date']);
                    }
                }).end().end()

Open the browser debugger and look at the implementation. See what animations are connected, what events are hung. Where are they from, from which file, and what files are loaded on the page
