 React has implemented a browser-independent events and DOM system for performance and cross-browser compatibility reasons. We took the opportunity to clean up a few rough edges in browser DOM implementations.

+Beside [DOM differences](/react/docs/dom-differences.html), React offers some attributes that simply don't exist in DOM.
+
+- `key`: an optional, unique identifier. When your component shuffles around during `render` passes, it might be destroyed and recreated due to the diff algorithm. Assigning it a key that persists makes sure the component stays. See more [here](/react/docs/multiple-components.html#dynamic-children).
+- `ref`: see [here](/react/docs/more-about-refs.html).
+- `dangerouslySetInnerHTML`: takes an object with the key `__html` and a DOM string as value. This is mainly for cooperating with DOM string manipulation libraries. Refer to the last example on the front page.
