      函数: useLayoutEffect() 

      function useLayoutEffect(effect: EffectCallback, deps?: DependencyList): void

      useLayoutEffect is now an alias of useEffect. Use useEffect instead.

      Accepts a function that contains imperative, possibly effectful code. The effects run after main thread dom update without blocking it.

      参数

      范围类型描述
      effectEffectCallbackImperative function that can return a cleanup function
      deps?DependencyListIf present, effect will only activate if the values in the list change (using ===).

      返回

      void

      已被弃用

      useLayoutEffect in the background thread cannot offer the precise timing for reading layout information and synchronously re-render, which is different from React.
