看了官方文檔，沒想明白是干什么的，和Route的render屬性有什么區(qū)別？const OldSchoolMenuLink = ({ label, to, activeOnlyWhenExact }) => ( <Route path={to} exact={activeOnlyWhenExact} children={({match}) => ( <div className={match ? 'active' : ''}> {match ? '>' : ''}<Link to={to}>{label}</Link> </div> )}></Route>);

找到官方解釋了

Sometimes you need to render whether the path matches the location or not. In these cases, you can use the function children prop. It works exactly like render except that it gets called whether there is a match or not.
