React hooks for utils

[user753]

I think it would be useful to have build in react hooks for subscribe, subscribeKey, etc. Something like

export function useSubscribe<T extends object>(proxyObject: T, callback: () => void, notifyInSync?: boolean) {
  useEffect(() => {
    return subscribe(proxyObject, callback, notifyInSync)
  }, [callback, notifyInSync, proxyObject])
}

export function useSubscribeKey<T extends object, K extends keyof T>(proxyObject: T, key: K, callback: (value: T[K]) => void, notifyInSync?: boolean) {
  useEffect(() => {
    return subscribeKey(proxyObject, key, callback, notifyInSync)
  }, [callback, key, notifyInSync, proxyObject])
}

We don't add such utils here, but feel free to create a third-party package if you think it's useful.

Note that you can use arrow function:

export function useSubscribe(proxyObject, callback, notifyInSync) {
  useEffect(
    () => subscribe(proxyObject, callback, notifyInSync),
    [proxyObject, callback, notifyInSync]
  )
}

But why?

It's our design decision is to provide primitive features from core.
