题目

一个数组怎样过滤另一个数组中的值，如下图和代码
一个数组具有悉数数据
另一个数组只具有部份数据
具有悉数数组数组要根据具有部份数据的数组，过滤获得新的数组

代码

具有悉数数据的数组

      let allRoutes = [
        {
          path: '/',
          name: 'home',
          component: () => import('@/views/Home.vue'),
          children: [
            {
              path: '/role',
              name: 'role',
              meta: {
                tile: '角色'
              },
              component: () => import('@/views/role/index.vue'),
              redirect: '/role/list',
              children: [
                {
                  path: 'create',
                  name: 'roleCreate',
                  meta: {
                    tile: '建立角色'
                  },
                  component: () => import('@/views/role/create.vue')
                },
                {
                  path: 'list',
                  name: 'roleList',
                  meta: {
                    tile: '角色列表'
                  },
                  component: () => import('@/views/role/list.vue')
                },
                {
                  path: 'update',
                  name: 'roleUpdate',
                  meta: {
                    tile: '修正角色'
                  },
                  component: () => import('@/views/role/update.vue')
                }
              ]
            },
            {
              path: '/adminUser',
              name: 'adminUser',
              meta: {
                tile: '管理员'
              },
              component: () => import('@/views/adminUser/index.vue'),
              children: [
                {
                  path: 'create',
                  name: 'adminUserCreate',
                  meta: {
                    tile: '建立管理员'
                  },
                  component: () => import('@/views/adminUser/create.vue')
                },
                {
                  path: 'list',
                  name: 'adminUserList',
                  meta: {
                    tile: '管理员列表'
                  },
                  component: () => import('@/views/adminUser/list.vue')
                },
                {
                  path: 'update',
                  name: 'adminUserUpdate',
                  meta: {
                    tile: '修正管理员'
                  },
                  component: () => import('@/views/adminUser/update.vue')
                }
              ]
            }
          ]
        },
        {
          path: '*',
          name: '404',
          component: () => import('@/views/404.vue')
        }
      ]

具有部份数据的数组

比拟悉数数据的数组，没有了name: 'roleCreate',

      let someRoutes = [
        {
          name: 'home',
          children: [
            {
              name: 'role',
              children: [{ name: 'roleList' }, { name: 'roleUpdate' }]
            },
            {
              name: 'adminUser',
              children: [
                { name: 'adminUserCreate' },
                { name: 'adminUserList' },
                { name: 'adminUserUpdate' }
              ]
            }
          ]
        }
      ]
