const routes = [
  {
    path:"/HelloWorld",
    component: HelloWorld
  },
  {
    path: "/second",
    component: second
  },
  //
  {
    path: "/",
    redirect: HelloWorld
  }
]A second route is always displayed when it comes in. Click to switch, and set the default HelloWorld to make the initial route invalid. What"s the matter? (beginners of vue)
