BREAKING CHANGE: `createApp` API has been adjusted.
- `createApp()` now accepts the root component, and optionally a props
object to pass to the root component.
- `app.mount()` now accepts a single argument (the root container)
- `app.unmount()` no longer requires arguments.
New behavior looks like the following:
``` js
const app = createApp(RootComponent)
app.mount('#app')
app.unmount()
```
@vue/runtime-dom
import { h, createApp } from '@vue/runtime-dom'
const RootComponent = {
render() {
return h('div', 'hello world')
}
}
createApp().mount(RootComponent, '#app')
