The upcoming React 0.12 tweaks some APIs to get us close to the final 1.0 API. This release is all about setting us up for making the `ReactElement` type really FAST, [jest unit testing](https://facebook.github.io/jest/) easier, making classes simpler (in preparation for ES6 classes) and better integration with third-party languages!
**React** is worked on full-time by Facebook's product infrastructure and Instagram's user interface engineering teams. They're often around and available for questions.
In React, you can create distinct components that encapsulate behavior you need. Then, you can render only some of them, depending on the state of your application.
We wrote this document so that you have a better idea of how we decide what React does and what React doesn't do, and what our development philosophy is like. While we are excited to see community contributions, we are not likely to choose a path that violates one or more of these principles.
Internally, React uses several clever techniques to minimize the number of costly DOM operations required to update the UI. For many applications, using React will lead to a fast user interface without doing much work to specifically optimize for performance. Nevertheless, there are several ways you can speed up your React application.
React and [Web Components](https://developer.mozilla.org/en-US/docs/Web/Web_Components) are built to solve different problems. Web Components provide strong encapsulation for reusable components, while React provides a declarative library that keeps the DOM in sync with your data. The two goals are complementary. As a developer, you are free to use React in your Web Components, or to use Web Components in React, or both.
