Question - What is dynamic route matching? 
          
        
        Answer - 
        
Sometimes it may be required to map routes to the same component based on a pattern.
Let's take a user component with the mapped URLs like /user/john/post/123 and /user/jack/post/235 using dynamic segments,
const User = {
  template: '
User {{ $route.params.name }}, PostId: {{ route.params.postid }}
'
}
const router = new VueRouter({
  routes: [
    // dynamic segments start with a colon
    { path: '/user/:name/post/:postid', component: User }
  ]
})
