 React is a JavaScript library for building user interfaces.
 
-* **Declarative:** React uses a declarative paradigm that makes it easier to reason about your application.
-* **Efficient:** React computes the minimal set of changes necessary to keep your DOM up-to-date.
-* **Flexible:** React works with the libraries and frameworks that you already know.
+* **Just the UI:** Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.
+* **Virtual DOM:** React uses a *virtual DOM* diff implementation for ultra-high performance. It can also render on the server using Node.js — no heavy browser DOM required.
+* **Data flow:** React implements one-way reactive data flow which reduces boilerplate and is easier to reason about than traditional data binding.
