I'd point to that being a particular bad example. For one thing, you are going to have to enforce that business logic on the back end or your data structures will get shredded.
If one thing drives me crazy about the current situation it is the techniques you found on the most advanced web sites in 1999 are effectively lost, like the techniques used to build the Egyptian pyramids. Redrawing the whole page can be amazingly fast over a fast network (LAN/localhost which is a real situation in the enterprise) if you aren't loading 50x more CSS than you need and not loading 300 trackers or having a real time auction with 10,000 bidders for ads -- that kind of app can feel more responsive than many desktop and mobile applications today.
I have no doubt whatsoever that you could make an issue tracker with HTMX which would embarrass JIRA.
What amazes me about React though is that I can literally walk around inside a React web page, see
and when I look at things like Vue and Svelte I see a lot of things that "look like a good mental modal for everyday web applications" but with React I can "draw anything I want" Thing is that people mostly want to make form applications and the framework that would serve them best is something like react-hook-form with a simpler substrate than React underneath it.
Right now I am working on biosignals demos where I might have a radar that reads respiration and a heart rate monitor and a myoelectric sensor and it is really easy to snap together a few components in JSX and write a little bit of code that fetches data from the devices and uses a library of functions to process it for the components. It should be just as easy to drag and drop a few components from a visual palette and configure them on the fly but React is not good for that.
Back in 2006 I was working on Javascript systems such as decision support applications and knowledge graph editors that were that flexible and... the rest of the world just hasn't caught up.
