I would love for the authors to consider a book on Hyperscript.
I initially dismissed wanting to add another scripting language to an app, but after some experimenting I have used it to replace 100s of lines of JS. Mainly for UI animations.
It’s not for the faint of heart, but enjoyable to learn.
I find the docs difficult to follow and would enjoy another hardback manual to sit next to this book, which is superb.
