API that returns Promise?

[lffg]

I think that the "way of doing async stuff" in JavaScript has significantly evolved in the past few years. We are moving to promises that empower the developers to make use of the async/await APIs.

With that, I truly think that callback APIs are slowing this process and making it more difficult.

Then I ask: Why is this library still uses callbacks to handle its async methods?
