no shadow dom, less state complexity

useSignal?

Solid.js and many other tools implement a new way for managing "app state"

useSignal() is the Future of Web Frameworks

The key difference between Signals and State is that Signals return a getter and a setter, 

whereas non-reactive systems return a value (and a setter).

Why is returning a getter (function) better than returning a value?
Because by returning the getter, you can separate the passing of the state-reference from a reading of the state-value.
