 While Vue scales up just as well as, if not better than React, it also scales down just as well as jQuery. That's right - all you have to do is drop a single script tag into a page:
 
 ``` html
-<script src="https://unpkg.com/vue@next/dist/vue.js"></script>
+<script src="https://unpkg.com/vue/dist/vue.js"></script>

 Then you can start writing Vue code and even ship the minified version to production without feeling guilty or having to worry about performance problems.

 While Angular 1 could be used for smaller applications, Angular 2 has shifted focus to best facilitate large enterprise applications. As part of this, it almost requires TypeScript, which can be very useful for developers that desire the type safety of languages such as Java and C#.

-Large applications can often grow in complexity, due to multiple pieces of state scattered across many components and the interactions between them. To solve this problem, Vue offers [vuex](https://github.com/vuejs/vuex/tree/next): our own Elm-inspired state management library. It even integrates into [vue-devtools](https://github.com/vuejs/vue-devtools), providing zero-setup access to time travel.

 As we continue developing the convention where components are never allowed to directly mutate state that belongs to a store, but should instead dispatch events that notify the store to perform actions, we eventually arrive at the [Flux](https://facebook.github.io/flux/) architecture. The benefit of this convention is we can record all state mutations happening to the store and implement advanced debugging helpers such as mutation logs, snapshots, and history re-rolls / time travel.
