Item Flow, Part 1: A new unified concept for layout
(webkit.org)
CSS Grid and Flexbox brought incredible layout tools to the web, but they don’t yet do everything a designer might want. One of those things is a popular layout pattern called “masonry” or “waterfall,” which currently still requires a Javascript library to accomplish.

We shrunk our Javascript monorepo git size
(jonathancreamer.com)
This isn't click bait. We really did this! We work in a very large Javascript monorepo at Microsoft we colloquially call 1JS. It's large not only in terms of GB, but also in terms of sheer volume of code and contributions. We recently crossed the 1,000 monthly active users mark, about 2,500 packages, and ~20million lines of code! The most recent clone I did of the repo clocked in at an astonishing 178GB.
