[Vuejs]-Fresh Laravel 9 installation with vue 3 scaffold and vite not redering component

So i changed the boilerplate code in my resouces/js/app.js file and it worked. i don’t know why.

i changed this

import './bootstrap';
import { createApp } from 'vue';

const app = createApp({});
import ExampleComponent from './components/ExampleComponent.vue';

app.component('example-component', ExampleComponent);
app.mount('#app');

to this

import './bootstrap';
import { createApp } from 'vue';
import ExampleComponent from './components/ExampleComponent.vue';

createApp(ExampleComponent).mount('#app');
