A language/framework that explored well this idea is Elm, which is used in front-end apps. It started with Signals and FRP, then 7 years ago changed course to the Model-View Update architecture [1], today known as The Elm Architecture. It is still a bit niche, but a handful of frameworks in other languages like Rust are following this architecture for GUI apps.
