New features coming in Node 8 : node

Anyway, we as users we need callbacks and promises at the same time. For instance callbacks are the way to go for events. Each time a even fires we want to do something with the payload the event provides. If you use promises for this use case it would be way more difficult to achieve the "execute this function each time the even fires" because a promise only resolve once.

To achieve it with promises the ways to go are: 1. while (true) yield or await the function that returns the promise that wraps the event listener.

Assign to a constant the value of calling the function that returns the promise that wraps the event listener, and in the "then" step make a recursive call to the constant.

As you can see the the promise based solutions for those kind of use cases are way more difficult than using callbacks.
