Thanks Ken for the clear explanations and illustrations of the methods. I loved the embedded version of the "instant rimshot" by the way 😃

I was familiar with most of it, but the timeout ones are new to me and definitely useful. Before I used to use Awaitility which requires importing an extra library. As always your teaching style, pace and jokes are greatly appreciated. Thanks for the effort.
