I'm not well versed in React so only clicked into this article out of mild curiosity. If anyone is interested in discussing the non-technical aspects of this submission, please continue reading this comment :)

What do people think of the foray of these blog posts with embedded javascript components? It appears that this a nice way to provide interactive explanation on subjects. I think this post does a nice job. That said, the website experience is always a little off when someone uses components like this. For example, if you open the page and quickly scroll down, you get lots of flashes of the page layout changing. Also, the back history button seems to be broken after visiting this page. I think the website pushes itself to the browser history or something?
