Another thing is that this looks like any other framework out there. I think you can map every one of it's features mostly 1-1 to SolidJS. What is the novelty here? The slightly changed js syntax with "component", "@" and "#"?
I would like to see more radical and new ideas in the js space, expecially in this period. Maybe a new take on Elm to get stronger UI stability guarantees. Or even just some very good tooling to reason about very large reactivity graphs at runtime and (maybe also at) compile time.
That said I still appreciate the work and in particular all the effort spent making the new syntax work in all common editors, I see they support vscode, intellij, sublime, ...
Edit: In the actual documentation they provide an llm.txt https://www.ripplejs.com/llms.txt
