问在Vue CLI中导入文件说明(应用程序与App.vue之间的区别)

EN

// Import vue in itself
import Vue from 'vue'

// Import the App component, you can see it as the root of your app that will contain all of your other components
import App from './App.vue'

// Create a new javascript instance of vue
new Vue({
    render: h => h(App), // This new instance will render the app component
}).$mount('#app') // Actually mount the whole application targeting the #app id in the DOM
