Getting started with a Vue component

Vue components are the main building blocks for Vue.js applications. A component consists of template syntax, script, and style.

</template>
<script lang="ts">
import { defineComponent } from "vue";
import HelloWorld from "./components/HelloWorld.vue";
export default defineComponent({
  name: "App",
  components: {
    HelloWorld
  }
});
</script>
<style>
#app {

  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center...
