Is it correct to include third-party scripts in App.vue using Vue CLI?

Question

Electronic components

I just had an interview, there was a question regarding my test task.
The App.vue root component had the following picture:

<script src="./assets/bootstrap/js/bootstrap.min.js"></script>
<script>
  Date.prototype.yyyymmdd = function() {
    var mm = this.getMonth() + 1
    var dd = this.getDate()
    return [this.getFullYear(),
      ( mm > 9 ? '' : '0' ) + mm,
      ( dd > 9 ? '' : '0' ) + dd
    ].join('')
  }
  
  export default {
    data() {
      return {
        menuShow: false,
        linkMenu: [
          { title: 'Home', url: '/' },
          { title: 'All Tasks', url: '/tasks' }
        ]
      }
    }
  }
</script>

There was a question next "How correct is the connection of the bootstrap script and the connection of the method of the Date object inside the App.vue component?"

Answer 1

In my opinion, it would be correct to install bootstrap via npm, import it into main.js and make some global settings there.
