 In large applications, we may need to divide the app into smaller chunks and only load a component from the server when it's needed. To make that possible, Vue has a `defineAsyncComponent` method:
 
 ```js
-const app = Vue.createApp({})

 If you only need very simple routing and do not wish to involve a full-featured router library, you can do so by dynamically rendering a page-level component like this:
 
 ```js
+const { createApp, h } = Vue
+
 const NotFoundComponent = { template: '<p>Page not found</p>' }
 const HomeComponent = { template: '<p>Home page</p>' }
 const AboutComponent = { template: '<p>About page</p>' }

 Combined with the [History API](https://developer.mozilla.org/en-US/docs/Web/API/History_API/Working_with_the_History_API), you can build a very basic but fully-functional client-side router. To see that in practice, check out [this example app](https://github.com/phanan/vue-3.0-simple-routing-example).

 It is often overlooked that the source of truth in Vue applications is the reactive `data` object - a component instance only proxies access to it. Therefore, if you have a piece of state that should be shared by multiple instances, you can use a [reactive](/guide/reactivity-fundamentals.html#declaring-reactive-state) method to make an object reactive:
 
 ```js
-const sourceOfTruth = Vue.reactive({
+const { createApp, reactive } = Vue
+
+const sourceOfTruth = reactive({
   message: 'Hello'
 })
 
-const appA = Vue.createApp({

 Now whenever `sourceOfTruth` is mutated, both `appA` and `appB` will update their views automatically. We have a single source of truth now, but debugging would be a nightmare. Any piece of data could be changed by any part of our app at any time, without leaving a trace.
