const app = Vue.createApp({
  data() {
    return {
      currentTab: 'Home',
      tabs: ['Home', 'Posts', 'Archive']
    }
  },
  computed: {
    currentTabComponent() {
      return 'tab-' + this.currentTab.toLowerCase()
    }
  }
})

app.component('tab-home', {
  template: `<div class="demo-tab">Home component</div>`
})
app.component('tab-posts', {
  template: `<div class="demo-tab">Posts component</div>`
})
app.component('tab-archive', {
  template: `<div class="demo-tab">Archive component</div>`
})

app.mount('#dynamic-component-demo')
