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 is a JavaScript library for creating user interfaces by Facebook and Instagram. Many people choose to think of React as the V in MVC.
We built React to solve one problem: building large applications with data that changes over time. To do this, React uses two main ideas.
Simple
Simply express how your app should look at any given point in time, and React will automatically manage all UI updates when your underlying data changes.
Declarative
When the data changes, React conceptually hits the "refresh" button, and knows to only update the changed parts.
Build Composable Components
React is all about building reusable components. In fact, with React the only thing you do is build components. Since they're so encapsulated, components make code reuse, testing, and separation of concerns easy.
Give It Five Minutes
React challenges a lot of conventional wisdom, and at first glance some of the ideas may seem crazy. Give it five minutes while reading this guide; those crazy ideas have worked for building thousands of components both inside and outside of Facebook and Instagram.
