const HelloWorld = {
  data() {
    return {
      message: 'Hello, Vue!'
    };
  },
  created() {
    console.log('Component created');
  },
  mounted() {
    console.log('Component mounted');
  },
  updated() {
    console.log('Component updated');
  },
  destroyed() {
    console.log('Component destroyed');
  },
  template: `
    <div>
      <p>{{ message }}</p>
    </div>
  `

p.s 適用不同裝置顯示:

<meta name="viewport" content="width=device-width, initial-scale=1.0">

<script>
const app = Vue.createApp({})
 
app.component('site-name', {
  props: ['title'],
  template: `<h4>{{ title }}</h4>`
})
 
app.mount('#app')
</script>
