The callback should be called with the data.

task.callback();

The logic inside execute is not fixed. I think even the logic has to be passed somehow as callback.
In this code, it is ajax. but async task can be anything.

Yep. this library shouldn't assume you have to do an ajax.
In execute just call the callback with err or data.

// task => {

Here asyncTask must return a Promise
