Lots of bits and pieces this week like running JavaScript on MS-DOS(!?), a deep dive on a V8 optimization, writing React apps on top of Ruby on Rails, a JS runtime for a tiny microcontroller, and, oh, a huge Node release..

JavaScript Weekly

Lexical: An Extensible Text Editor Library (That Does Things Differently) — Fresh from Meta (or Facebook, as my brain still calls it) comes a new text editor framework with accessibility, performance, and reliability at its heart. 22KB gzipped, supports React 18 (but can be used in a vanilla fashion), and a (native) iOS version is to follow. Remind you of Draft.js? Think of this as the next generation: Meta is – they’re replacing Draft with Lexical in their apps.

Meta / Facebook

Node.js 18 (Current) Released — We get V8 10.1, Undici-powered global Fetch API support, Web Streams API support, Blob and BroadcastChannel APIs, the new test runner module, and the ability to create your own Node.js binaries with custom V8 startup snapshots. Node 18 goes LTS from October, but gets all the latest features until then.

The OpenJS Foundation's JavaScriptLandia Awards — Back in 2020, the OpenJS Foundation launched JavaScriptLandia as a sort of way to express support for the JS ecosystem, but here’s a practical result of it: you can nominate anyone in the JS ecosystem for an award for the hard work they do. So, um, yeah, find your favorite new library and nominate its creator, perhaps?
