BrowserLab: Automated regression detection for the web
https://code.facebook.com/posts/1368798036482517/browserlab-automated-regression-detection-for-the-web/
Time spent in browser rendering and scripting has grown to become a major bottleneck in loading facebook.com — at the beginning of 2016, we found that the majority of load time was spent on the client. To solve this problem, we set out to build a system capable of detecting changes in performance that can run on any commit to automatically prevent client regressions from shipping to production.
另外 Facebook 还推出了Zstandard 1.0, a new compression algorithm and implementation designed to scale with modern hardware and compress smaller and faster.

https://medium.com/dev-channel/the-case-for-custom-elements-part-2-2efe42ce9133#.6hburcdgr
In this post I want to make the case for why I think Custom Elements make sense, especially for large organizations. In Part 2 I will present a deeper dive on the features that make Custom Elements so compelling. I’ll also explore topics often overlooked when discussing Custom Elements, such as their ability to work with Virtual DOM and be rendered on the server.

Ways To Reduce Content Shifting On Page Load
https://www.smashingmagazine.com/2016/08/ways-to-reduce-content-shifting-on-page-load/
Have you ever opened a website, started reading and, after some time had passed and all assets had finished loading, you found that you’ve lost your scroll position? I undergo this every day, especially when surfing on my mobile device on a slow connection — a frustrating and distracting experience. Any time a browser has to recalculate the positions of elements in a document, a reflow occurs which can affects performance and the user experience. How can these shifts be minimized?
