Reacton
Reacton is a React-like layer around ipywidgets.
Using a declarative way, in a React (JS) style, makes your codebase smaller, less error-prone, and easier to reason about. We don't see a good reason not to use it.
Also, React has proven itself, and by adopting a proven technology, we can stand on the shoulders of giants, make use of a lot of existing resources, and do not have to reinvent the wheel.
Solara or Reacton?
We consider Solara a superset of Reacton, and that's why the full namespace of the reacton package is imported into the solara package.
Therefore, you can write solara.use_state or reacton.use_state, they are the same function.
The reason for this is simplicity for newcomers, who don't care about the difference between solara and reacton.
But in practice, it also saves having to import both solara and reacton.
Also, when writing Solara based apps, one does not think about Reacton anymore, it is all Solara.
