CycleJS is a fully reactive JavaScript framework for Human-Computer Interaction

Cycle.js: a functional and reactive JavaScript framework for cleaner code.

Your app and the external world as a circuit:

Your app and the external world as a circuit:

Cycle’s core abstraction is that your application is a pure function: main(). A function where inputs are read (sources) from the external world and outputs (sinks) are written to the external world. These side effects in the external world are managed by drivers: plugins that handle DOM effects, HTTP effects, and other side effects.

The internals of main() are built using Reactive programming primitives, which maximize the separation of concerns, providing a clean and fully declarative way of organizing your code. The dataflow is plainly visible, making it easy to read and understand the code.

What is the XStream imitate use case

The docs go over imitate use case, but I don't understand the example made. Where would you call a Parent function, is it like recursive? I'd like to see what the model function looks like, and what the child gets out of it.
