how to use router object to go back in vue component code example

Example 1: go to next route vuejs

// literal string path
router.push('home')

// object
router.push({ path: 'home' })

// named route
router.push({ name: 'user', params: { userId: '123' } })

// with query, resulting in /register?plan=private
router.push({ path: 'register', query: { plan: 'private' } })

Example 2: navbar route with params vue

//if we have a route that admits params via url:
{path : '/page/:id?', name='page', component: Page},

  //we can edit the url to show the params we want like this:
<router-link :to="{name: 'page', params:{id: 'hello'}}"> </router-link>
