In React, a component’s internal state is kept to minimum because every time the state changes, the component is rendered again. The purpose of this is to have an accurate representation of the component state in your JavaScript code and let React keep the interface in sync.

For this reason, form components such as <input>, <textarea>, and <option> differ from their HTML counterparts because they can be mutated via user interactions.

Lately I’ve been using ReactJS a lot to build rich user experiences on the web, and it’s been absolutely great. A huge improvement over AngularJS in my humble opinion.

The only ugly spot with ReactJS is JSX. I can see the appeal of using declarative HTML in templates for readability, but having switched to HAML (and Slim and Jade) long ago, writing HTML feels like a step backwards.
