const routes = [
  {
    path: 'index',
    breadcrumbName: 'home',
  },
  {
    path: 'first',
    breadcrumbName: 'first',
    children: [
      {
        path: '/general',
        breadcrumbName: 'General',
      },
      {
        path: '/layout',
        breadcrumbName: 'Layout',
      },
      {
        path: '/navigation',
        breadcrumbName: 'Navigation',
      },
    ],
  },
  {
    path: 'second',
    breadcrumbName: 'second',
  },
];
function itemRender(route, params, routes, paths) {
  const last = routes.indexOf(route) === routes.length - 1;
  return last ? (
    <span>{route.breadcrumbName}</span>
  ) : (
    <Link to={paths.join('/')}>{route.breadcrumbName}</Link>
  );
}

return <Breadcrumb itemRender={itemRender} routes={routes} />;
```
