Online IDE in the documentation

Continuing the conversation on Twitter here: twitter.com/acemarke/status/913891217385168896.

I think it would be very beneficial for beginners to use CodeSandbox/Stackblitz/WebpackBin to start learning React. The environment is like a local code editor, which means that the user already gets familiar with the feel of a code editor. The user doesn't have to install any tooling, so you can start immediately. Also, whenever they want to continue offline they can easily click on 'Download'/'Export' to get a CRA version of the same application so they can work further on it.

I think we all agree that this would be beneficial, the question is how to approach this without confusing the user. Would be great to have a discussion on this here.

L’issue non indica file né test; inizia dalla discussione Twitter collegata e confronta gli approcci proposti di CodeSandbox, Stackblitz e WebpackBin. Il lavoro è completato quando è stato concordato un piano di integrazione per la documentazione React per principianti che eviti di confondere gli utenti e supporti l’esportazione di una versione CRA per lavorare offline.
