Hi there, glad to see hyperscript on HN again.
I started the project because I wanted an event-oriented scripting language that embedded well in the DOM, and I always missed HyperTalk, the old scripting language for HyperCard.
hyperscript isn't designed to be a general purpose programming language: it's designed for simple, client side DOM scripting. It has thinks like class literals (.foo) and so forth, and takes a lot of inspiration functionally from jQuery. It'd designed also to dovetail well with htmx, which triggers a bunch of events.
Happy to answer questions.
