It is not the same at all. Of course it needs javascript on the back to work.

But the concept is totally different. It uses a hypermedia declarative model, an extended POST/GET etc. model. It keeps things very simple compared to a framework like React where you need a package manager, a transpiler and a json backend for data (not returning hypermedia).

So I would not consider it another Javascript frontend framework at all. I would consider it more like original html with extensions that support Ajax respecting the original web model.
