I made games in flash for over a decade and miss the ease of dropping an experimental game idea onto the web where everyone could enjoy it. If you had a free weekend, you could release a game to 99% of the internet.
JavaScript game libs simply aren't as featureful, even the ones promising the scenegraph API. They don't work as well cross platform (by the end of that decade I had one codebase which could deploy to web, iOS, and Android); and that's where the audience has headed.
I hope this book spends some time on flash's contribution to video game design as well as web design.
also thousands of games made with pico8 on the net live. Sure pico-8 is not a replacement for flash but people are posting live games and they are making them quickly. Celeste, one of the top 10 games last year on many lists, started as a pico8 prototype live on the web.
Also flash never worked cross platform in the modern sense (phones + tablets + desktop). It's a very hard problem and no system I know of handles it automatically for anything more than simple HTML text forms
