LazilyLoad组件懒加载

Question

<LazilyLoad modules={{
  TodoHandler: () => importLazy(import('./components/TodoHandler')),
  TodoMenuHandler: () => importLazy(import('./components/TodoMenuHandler')),
  TodoMenu: () => importLazy(import('./components/TodoMenu')),
}}>
{({TodoHandler, TodoMenuHandler, TodoMenu}) => (
  <TodoHandler>
    <TodoMenuHandler>
      <TodoMenu />
    </TodoMenuHandler>
  </TodoHandler>
)}
</LazilyLoad>

以上这段代码是我从webpack官网看到的，这里有一个语法想不同，import("./path") import怎么能做函数调用呢？谁给一个解释呢
