Looking for Julia asynchronous coding and callback handling videos, examples or text?

Hi all
I am coming from python and learnt about how to handle asynch from the splendid Dave Beazley. I see lashings of asynch, callbacks and wrappers in my future so I want to make a good start. I have done the google search stuff so the basics are covered ie. https://docs.julialang.org/en/v1/manual/asynchronous-programming/ I’m looking for things that the community found useful when they were starting out.

So I am looking for collateral that the community consider to be helpful that cover the following julia specific topics:

  1. the handling of asynchronous events
  2. callbacks, uses and abuses of
  3. wrappers

thank you
