Animations are for APPS not ebooks.

And I do know about javascript.

I do know about multimedia design & websites, inc server side code. More than 20 years experience.

I know about writing apps, desktop programs and video production.

Once you add animation or interaction or video or sound, it's no longer a book. It's best done as an app and not pretending to be a book.

Poetry works fine in epub2.

Javascript is a stupid lazy way to do static layout, which is all an ebook should have.


We have different definitions of what an eBook is.

But stop being insulting just because you are an avid promoter of the epub3 spec.

The OP and title is about "javascript in epub". My point is that most ebook sales and most physical ereaders and the store apps don't have javascript. If javascript is really needed it's not a real ebook. Sure you can use epub3. Good luck on selling that with working javascript in the major selling ebook stores compared with better features in an iOS and Android app.
