VueRouter学习01-基本使用
## 基本使用：
1. 创建一个`VueRouter`对象：`new VueRouter()`。
2. 在`VueRouter`中，需要传递一个`routes`参数。这个参数是一个数组类型，数组中存储的是对象，对象中最少要有两个属性，一个是`path`，代表`url`，第二个是`component`，代表数据更新的组件。示例代码如下：
```js
let router = new VueRouter({
routes: [
{path: "/",component: index},
{path: "/find",component: find},
{path: "/friend",component: friend}
]
})
```
