reactjs - 我应该将 setState 包含在 useCallback 的依赖项数组中吗？

Question

    const [active, setActive] = useState(false);

    const onActiveChanged = useCallback(
      isActive => () => {
        // do something
        setActive(isActive);
      },
      [setActive], // or just [] is okay?
    );

当同时使用 useState 和 useCallback (或 useMemo)时，我应该在数组中包含 setState依赖关系？

Answer 1

对此的建议也在React Docs - Hooks API Reference上.

The setState function is used to update the state. It accepts a new state value and enqueues a re-render of the component.

setState(newState);

During subsequent re-renders, the first value returned by useState will always be the most recent state after applying updates.

Note

React guarantees that setState function identity is stable and won’t change on re-renders. This is why it’s safe to omit from the useEffect or useCallback dependency list.
