I think Hyperscript is easy to bash on due to it's _very_ different syntax than what programmers are normally used to. That said, I think it's a really nice way to add little pieces of functionality without needing to bring out the JS frameworks.

It should be remembered that Hyperscript is meant to be paired with a technology like HTMX. I don't think the creator of Hyperscript would be suggesting to anyone that someone attempt to create a web application out of pure Hyperscript.
