Therefore, it seems like this is the appropriate place to introduce this concept.\r\n\r\nBesides improving the explanation for this to make a little more introductory, it seems like this should be added to the tutorial.  If the maintainers agree, should I update any other example files?"},"comment":{"url":"https://api.github.com/repos/facebook/react/issues/comments/153212816","html_url":"https://github.com/facebook/react/pull/5374#issuecomment-153212816","issue_url":"https://api.github.com/repos/facebook/react/issues/5374","id":153212816,"user":{"login":"facebook-github-bot","id":6422482,"avatar_url":"https://avatars.githubusercontent.com/u/6422482?v=3","gravatar_id":"","url":"https://api.github.com/users/facebook-github-bot","html_url":"https://github.com/facebook-github-bot","followers_url":"https://api.github.com/users/facebook-github-bot/followers","following_url":"https://api.github.com/users/facebook-github-bot/following{/other_user}","gists_url":"https://api.github.com/users/facebook-github-bot/gists{/gist_id}","starred_url":"https://api.github.com/users/facebook-github-bot/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/facebook-github-bot/subscriptions","organizations_url":"https://api.github.com/users/facebook-github-bot/orgs","repos_url":"https://api.github.com/users/facebook-github-bot/repos","events_url":"https://api.github.com/users/facebook-github-bot/events{/privacy}","received_events_url":"https://api.github.com/users/facebook-github-bot/received_events","type":"User","site_admin":false},"created_at":"2015-11-03T01:37:42Z","updated_at":"2015-11-03T01:37:42Z","body":"Thank you for your pull request and welcome to our community.
