⚡️ IN BRIEF:
TC39’s Hemanth.HM has begun keeping a list of ES2023 code examples like he did for ES2022, ES2021, and ES2020.
🤔 The New Stack has a story about Meta supporting the OpenJS Foundation – but who wrote the article is what we found more interesting..

One downside to platforms like Cloudflare Workers using V8 isolates has been a lack of support for opening TCP sockets – quite an impediement if you want to talk to a RDBMS over TCP or something. Fear no more, Cloudflare Workers has introduced a connect() API for creating TCP sockets from Workers functions.
Promise.withResolvers progressed to stage 2 at the latest TC39 meeting.
↳ The formatter/linter gains stage 3 decorator support.

Starry Night: GitHub-Like Syntax Highlighting — Apparently, GitHub’s own syntax highlighting approach isn’t open source, but this takes a similar approach and is. It’s admittedly quite ‘heavy’ (due to using a WASM build of the Oniguruma regex engine) but that’s the price of quality.
