How to recursively call a function given in a variable?

Question

JavaScript

Simplified function code:

var func = function(items, errors) {
    if (items.length) {
        $.post(
            '/items/add/',
            {id: items.pop()},
            function (response) {
                if (typeof response.error != 'undefined') {
                    errors.push(response.error);
                } else {
                    // как осуществить вызов функции из переменной func (рекурсивный вызов)? 
                    ...(items, errors);
                }
            },
            'json'
        );
    } elseif (errors.length) {
        alert(errors.join(' '));
    }
};

func(new_items, []);

I am not familiar with JS, so the only thing that came to my mind was to pass the variable that stores the function as one of the parameters when calling, i.e.:

var func = function(fself, items, errors) {
    ...
    fself(fself, items, errors);
    ...
};
func(func, new_items, []);

in extreme cases, you can specify the name of the function:

function func(items, errors) {
    ...
    func(items, errors);
    ...
}
func(new_items, []);

The question is, is it possible to somehow recursively call such an anonymous function without explicitly passing this function to itself?

Answer 1

Do you mean so?

var func = function funcSelf(items, errors) { 
     // тут всякий код
     funcSelf(); // вызываем, используя имя funcSelf, которое доступно только внутри функции
}
