Which is better to use async.js or promise?

Question

JavaScript

Good day!
What is the best way to organize asynchronous code in Node.js? The old-fashioned way through callback noodles wrapped in async.js or through yield and promise?
Which option is more reliable and convenient? (because I just recently started working with promise, I felt something wet in my ear. I felt it, and it turns out that the brain is leaking).
PS Also, where can we use yield besides asynchronous code?

Answer 1

The fastest and most reliable is callback hell, go back to basics.

Answer 2

Node Events

Answer 3

Pure promises are the same noodles, only in profile. Well, only the investment is reduced. Generators and yield look better.
