Unfortunately the big game is opaque it's close to impossible to understand for the common folk. So many questions, so tough to grasp answers. Sickening. The enemy is hiding. One could say that paying the taxes in some form is a path toward a destruction. Phrases like "war economy" are lunatic. It all starts in your mind, and that's why it's the most important to protect your children from the propaganda. Take care!

It might be like that. Everyone should strive to make the best decisions and not go with the mainstream. Always question the mainstream, it's dangerous. Make a change for the better. Everything starts with you. Then your family, friends, neighbors... Do you have the opportunity to grow something yourself? Do that.

My company tried it but reverted the changes. The biggest reasons - it's not compatible with mobx and we didn't notice any perf gains on an existing codebase.

Do you find anything "bad" about this code solving the problem?

    use std::rc::Rc;
    use std::cell::RefCell;
    
    struct Button {
        text: String,
        on_click: Option<Rc<dyn Fn()>>,
    }
    
    impl Button {
        fn new(text: &str) -> Self {
            Button { text: text.to_string(), on_click: None }
        }
        fn draw(&self) { println!("[Button: \"{}\"]", self.text); }
        fn fire_click(button: &Rc<RefCell<Button>>) {
            let cb = button.borrow().on_click.clone();
            if let Some(cb) = cb {
                cb();
            }
        }
    }
    
    fn main() {
        let button = Rc::new(RefCell::new(Button::new("Click me")));
        let cb_handle = Rc::clone(&button);
    
        button.borrow_mut().on_click = Some(Rc::new(move || {
            cb_handle.borrow_mut().text = "Clicked!".to_string();
        }));
    
        button.borrow().draw();
        Button::fire_click(&button);
        button.borrow().draw();
    }
Prints:
  [Button: "Click me"]
  [Button: "Clicked!"]

Totally agree. One might require to be "in their head" a lot of the time to not get swung down, and enjoy himself such as laughing at his own jokes. To make it possible, one has to be free enough to express oneself (also internally). But freedom of thought and action is on the decline as I've come to observe lately, but that's another topic.

Yes, that's an OK take, no big deal. Also it can be added that life in itself really doesn't have a choice, on some level it just happens (thinking more about chemistry here).

"This is the famous UI = f(state) mental model of React". Famously incorrect generalization. Why? For example, the useRef hook enables components to hold their own state. React components are not guaranteed to be pure functions. Of course, it can depend on how one writes their code, but it's not a guaranteed that UI = f(state) in React in general.
