Great stuff. Can anyone recommend a library for throttle/debounce? In the vue world we have VueUse for this sort of thing.

    timeout = timeout ?? 500;
    const timeoutId = setTimeout(fn, timeout);

        }
    };
};

I use aHooks and it really matter, because you can define what you need to execute on throttle or debounce. Also this lib can deal with loading status, auto refresh, etc.
