Hi, What is a best FP approach while working on a JavaFX/TornadoFX project in terms of mutability? In controllers, event handlers I can do it in a FP style (thanks to kotlin and arrow) but when it comes to the side effects (displaying the information in UI) I don’t really know how to approach it. If I remember well in scalaz there is a IOMonad (and others similar). Thank you in advance for any guidance in the right direction regarding this.
