Difference between async/await and ES6 yield with generators

Question

I was just reading this fantastic article «Generators» and it clearly highlights this function, which is a helper function for handling generator functions:

Answer 1

In many ways, generators are a superset of async/await. Right now async/await has cleaner stack traces than co, the most popular async/await-like generator based lib. You can implement your own flavor of async/await using generators and add new features, like built-in support for yield on non-promises or building it on RxJS observables.

So, in short, generators give you more flexibility and generator-based libs generally have more features. But async/await is a core part of the language, it's standardized and won't change under you, and you don't need a library to use it. I have a blog post with more details on the difference between async/await and generators.
