How, using needle, sending a get request to return a value from the callback?

Question

JavaScript

This code for sending a get request outputs a large object with a bunch of properties. I need to get what I returned with "return"

function findMaxID() {
    var a = needle.get(URL, function(err, res){
        if (err) throw err;
        return 222; 
    });
    console.log(a);
}

No way with return. Only callbacks/promises. This is an asynchronous request.

function findMaxID(cb) {
    needle.get(URL, cb);
}

findMaxID(function(err, res){
    if (err) throw err;
    console.log(res); // -- данные доступны здесь
});
