> Stateful components don't work so well in React. If you want to update props in a stateful component, the recommendation is to replace the component entirely by changing its key.

Do you have any concrete examples for this? I'm not sure I agree: I've made plenty of stateful components in React and they are just fine. If anything, they're a lot cleaner than what I could do in plain JavaScript, thanks to the framework.

Further, could you expand on what you mean re: recommending changing the key? I have never heard the React team suggesting to do this, although maybe I missed something in the documentation :-)
