You can check out a live example [here](https://jsfiddle.net/yyx990803/4xfa2f19/).


You can make a parameter optional by adding `?` to the end of the parameter.

```js
const router = new VueRouter({
routes: [
//
{ path: '/user/:id?', component: Users }
]
})
```


You can have multiple dynamic segments in the same route, and they will map to corresponding fields on `$route.params`. Examples:

| pattern | matched path | \$route.params |
