          Counter: {{ counter }}
        </div>
        <script type="text/javascript">
            const Counter = {
              data() {
                return {
                  counter: 0
                }
              },
              mounted(){
                  setInterval(()=>{
                      this.counter++
                  },1000)
              }
            }

            </span>
        </div>

                data(){
                    return {
                        message: 'You loaded this page on' + new Date().toLocaleString()
                    }
