But before that, handling asynchronous code was quite more complex and difficult.

In previous versions of Python, you could have used threads or [Gevent](https://www.gevent.org/). But the code is way more complex to understand, debug, and think about.

In previous versions of NodeJS / Browser JavaScript, you would have used "callbacks". Which leads to "callback hell".
