Here is a comparison of `asyncio` (Python), `async` (Ruby) and Go: https://github.com/socketry/async-await/tree/master/examples...

I wrote a similar article but for Ruby: https://www.codeotaku.com/journal/2018-06/asynchronous-ruby/...

Yes, it's a good model for many use cases.

One thing I wondered about Ruby, is it really necessary to have the `await` keyword?

`await` is useful since with the absence of it you can schedule multiple tasks concurrently. In JS:

    var task1 = someAsyncTask1()
    var task2 = someAsyncTask2()
 
    await Promise.all([task1, task2])

If `await` was implicit then task2 would wait for task1 to finish.
