Upgrade to Jekyll 3 Full list of changes is at https://jekyllrb.com/docs/upgrading/2-to-3/. The tl;dr of it is: - Relative permalinks were removed, so all the files in the `docs` subdirectory need their permalink to be prefixed with `docs/` - `post` and `page` types were renamed to `posts` and `pages` respectively - `jekyll-paginate`, `pygments` and `redcarpet` are all now optional, so I needed to explicitly add it to the Gemfile. Jekyll now uses `rouge` rather than `pygments` for syntax highlighting, but rouge does not support highlighting individual lines (`hl_lines`) so we need to continue using Pygments. - Layout metadata (eg. `sectionid`) is now on a `layout` variable rather than `page` Tested the following pages and confirmed that they all work: - "Docs" link (getting started page): http://127.0.0.1:4000/react/docs/getting-started.html - Downloads: http://127.0.0.1:4000/react/downloads.html - Tutorial: http://127.0.0.1:4000/react/docs/tutorial.html - A few pages under the "docs" subdirectory, to confirm they're working properly: - http://127.0.0.1:4000/react/docs/addons.html - http://127.0.0.1:4000/react/docs/why-react.html - http://127.0.0.1:4000/react/docs/create-fragment.html - A few tips: - http://127.0.0.1:4000/react/tips/false-in-jsx.html - http://127.0.0.1:4000/react/tips/style-props-value-px.html - Non-English versions of the page: - http://127.0.0.1:4000/react/docs/getting-started-it-IT.html - http://127.0.0.1:4000/react/docs/getting-started-ja-JP.html

현재 컴포넌트의 `render`는 한 노드만 리턴할 수 있습니다. 만약 `div` 배열을 리턴하려면, `div`, `span`과 같은 다른 컴포넌트로 한 번 더 싸주어야 합니다.
JSX는 일반 JS로 컴파일 함을 잊지말아야 합니다. 두개의 함수를 리턴하는 것은 문법적으로 맞지 않습니다. 이와 마찬가지로, 한 삼항 연산자 안에 한개 이상의 자식 컴포넌트를 넣으면 안됩니다.
