在定義routes的時候：

const routes = [{
  path: '/',
  meta: {
    title: ''
  },
  component: (resolve) => require(['./views/index.vue'], resolve)
  children: [
    {
      path: '/a',
      name: 'a',
      title:'a',
      component: (resolve) => require(['./views/a.vue'], resolve)
    },
    {
      path: 'b',
      name: 'b',
      title:'b',
      component: (resolve) => require(['./views/b.vue'], resolve)
    },

  ]
}];

你看這里的children中的path,我見過有的有/，有的沒有。比如上面的path: '/a'和path:'b'。

請問這個有沒有區(qū)別呢？
