  breadcrumbName: 'home'
}, {
  path: 'first',
  breadcrumbName: 'first'
}, {
  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} />;
