📋 Description of content that is out-of-date or incorrect

These functions are not executed immediately, but instead are only called when the values they rely on are changed. When the underlying signal is changed, the function will be called again to produce a new value.

I'm beginning with solidjs, so maybe I got this wrong, but I think this is at least misleading.

It is not called when count() changed (click "call inc").
It is only called, if it is explicitly called (in the example click "call double") or if it is used in a reactive context (uncomment {/*<div>double: {double()}</div>*/})

🖥️ Reproduction in StackBlitz (if reporting incorrect content or code samples)

import { render } from "solid-js/web";
import { createSignal } from "solid-js";

function App() {
    const [count, setCount] = createSignal(0);

    const inc = () => setCount(count() + 1)
    const double = () => {console.log("double called"); return count() * 2}

    return (
        <div>
            <div>count: {count()}</div>
            {/*<div>double: {double()}</div>*/}
            <button onClick={() => inc()}>call inc</button>
            <button onClick={() => double()}>call double</button>
        </div>
    );
}

render(() => <App />, document.getElementById('app'));

Commencez par la page de documentation de derived-signals liée dans l'issue et comparez l'explication citée avec la reproduction SolidJS fournie. Mettez à jour la formulation afin qu'elle décrive correctement quand la fonction s'exécute, puis vérifiez l'exemple et le comportement qui en résulte dans la documentation.
