Regarding a modern alternative to Flash, I just want to mention the Scrimba webdev learning platform [1], which leverages a custom built programming language [2] for making interactive courses and save the videos in an optimized vector format with a very small footprint.
It was released in a Launch HN 3 years ago [3]. Personally, I have used the platform to teach the basics of frontend web dev to my wife, and it was a great experience.
