From SPA/Hybrid experience, you only mutate/change what actually needs to change, so in the example of the data-table, you can add/remove and don't have to reload/re-render the whole data-table, you can mutate element 1 or 1001 and only it will be effected without a server call (unless you updating in real time) but then you only send the minimal data. You can consume the same REST data API used by all your other applications regardless the client type i.e. browser, mobile app, electron etc. because the API is not concerned with the view/presentation, and I think this is where I have trouble understanding HTMX fully, do you need an API which purely respond with HTML (and embedded htmx), but what about other situations where you need Json or something else back?
