JS IF ELSE in JSON post request, how to implement?

Question

JavaScript

Data comes from the site form, I parse it and get data in json format, then I need to check whether the field is filled or not, if it is filled then pass it on in the post request, if not filled then do nothing.
The input looks like this -

I want to do a check, IF\ELSE.
If form.NAME = noone then nothing
Else "NAME" : form.NAME;
My script looks like this -

//Объявляю переменную
var formname = msg.form.NAME
//Служебная информация метода, url, тип данных
msg.headers = {}
msg.method = "POST"
msg.url = "http://127.0.0.1:1880/tst" ;
msg.headers["content-type"] = "application/json"
//Сам скрипт в msg.payload и есть тело запроса
msg.payload = {
    //если formname = noone, то пропускаем и ничего не делаем
    if (formname = 'noone') {
        //
    }
    //Иначе добавляем в тело "NAME" : formname
    else {
      "NAME": formname;  
    }
// Это просто данные в формате JSON
"PHONE":"[phone]",

};
//возвращаем в поток
return msg

But my script doesn't work, the validator throws errors

if is a language command, it cannot be inside a data declaration.

msg.payload = { PHONE: '[phone]', };
if (formname !== 'noone') {
  msg.payload.NAME = formname;
}
