reactjs - 延迟 @loadable/component 的加载

Question

当我有 10 秒的超时来加载页脚时，试图弄清楚为什么这两个同时加载。目前我正在同时获得两个负载。

   import loadable from '@loadable/component';
    
    const Footer = loadable(
        () =>
          new Promise(resolve =>
            setTimeout(() => resolve(import('src/Footer')), 10000), // 10 secondsdelay
          ),
      );
    
    const Layout = () = {
       return (
        <div>
           <div>RENDER RIGHT WAY</div>
            <Footer>
        </div>
       );
    }
