Update links to use https:// where it is supported. There's probably a lot more that could be fixed, but these are the core ones I found (especially the download links in order to prevent MITM attacks). Note that there are some fb.me links that will redirect to http:// even while accessed over https://, but this seemed like the best way to fix those for now. NOTE: Only non-third-party files were modified. There are references to http:// URLs in vendored/third-party files, but seems appropriate to fix upstream for those rather than editing the files. Also, copy one image locally to the blog, as it was hotlinking to a site that did not support https://. Last, use youtube-nocookie.com instead of youtube.com for video embeds, as the former doesn't try to set a cookie on load (privacy enhancement).

React 是一个 Facebook 和 Instagram 用来创建用户界面的 JavaScript 库。很人多认为 React 是 MVC 中的 V（视图）。
我们创造 React 是为了解决一个问题：构建随着时间数据不断变化的大规模应用程序。为了达到这个目标，React 采用下面两个主要的思想。
简单
仅仅只要表达出你的应用程序在任一个时间点应该长的样子，然后当底层的数据变了，React 会自动处理所有用户界面的更新。
声明式 (Declarative)
数据变化后，React 概念上与点击“刷新”按钮类似，但仅会更新变化的部分。
构建可组合的组件
React 都是关于构建可复用的组件。事实上，通过 React 你唯一要做的事情就是构建组件。得益于其良好的封装性，组件使代码复用、测试和关注分离（separation of concerns）更加简单。
给它5分钟的时间
React挑战了很多传统的知识，第一眼看上去可能很多想法有点疯狂。当你阅读这篇指南，请给它5分钟的时间；那些疯狂的想法已经帮助 Facebook 和 Instagram 从里到外创建了上千的组件了。
