前端项目实战叁佰陆拾陆react-admin和material ui-userMemo定义不可变的值

 const items = useMemo<INavItem[]>(() => {
    let navItems: INavItem[] = new Array<INavItem>();
 
    let plantModel: INavItem = {id: 1, open: false, title: '工厂建模', children: new Array<ISubItem>()};
    const plantmanager: ISubItem = {path: '/plantmodel/*', label: <NoneDecorationLink style = {{color: 'white'}} to = '/'>工厂管理</NoneDecorationLink>}
    plantModel.children.push(plantmanager);
    
    const testpage: ISubItem = {path: '/testpage/*', label: <NoneDecorationLink style = {{color: 'white'}} to = '/testpage'>测试路由</NoneDecorationLink>}  
    plantModel.children.push(testpage);
    navItems.push(plantModel);
 
    return navItems; 
  }, []);

运行结果
