Excited to share Nav262, our experimental IDE for navigating ECMA-262 algorithms, implemented by @albertotontoni.bsky.social at the University of Bergen. Repo: github.com/bldl/nav262

Landed a few improvements to the error reporting for require(esm) with top-level await (behind --experimental-print-required-tla for now): - No longer need to run the code to collect the TLA locations, so it can be enabled by default soon - Added require stack and location metadata to the error

Today a number of my Investec friends ran, walked and jogged from the City of London all the way to Twickenham and I got to see everyone! It was an absolutely beautiful and kind gesture - they are amazing ❤️

Bloomberg uses a lot of C++ & contributes to the standard as well as various industry conferences and libraries. I’m looking for an experienced engineer to join a distributed systems team in New York working on our core Deployment Infrastructure for the Bloomberg Terminal 🗽 🧵

We are so moved that we got to host this fantastic crowd in our humble corner of London 🥰 Much love to @npmx.dev community 🥰

Hello friends and welcome to another “how’s ESM vs CJS doing?!” A big win this time, at a year of `require(esm)` available! 38.0% of the popular npm packages now have ESM, up from 33.4% half a year ago. ESM-only is up from 12.6% to 16.0%. Particularly this non-dual, “vanilla” growth is very big!

Today is a big day for @socket.dev. We raised a $60M Series C at a $1B valuation, led by Thrive Capital. 20,000+ orgs, 1.5M repos protected, 1,000+ supply chain attacks blocked per week. 3/5 FAANG companies are customers. We're just getting started.

Landed a set of LLDB & GDB plugins in V8 to help inspect JS states in a live process/coredump together with native states ✨ The initial implementation just supports JS stack trace annotations in bt; support for object inspection is coming up! chromium.googlesource.com/v8/v8.git/+/...

Had a blast in London! Thanks @tchetwin.bsky.social, @legendecas.bsky.social and many volunteering Bloombergers for organising a great Node.js collab summit 😇 This was one of the most attended summits I’ve been to, so didn’t get to say hi to everyone, but very happy to see many new faces!

The recording of @jason-williams.co.uk talk ‘Temporal: It’s about time!’ is now available to watch online! 2026.stateofthebrowser.com/speaker/jaso... And Temporal has reached Stage 4: www.igalia.com/2026/03/13/T...

Temporal is now Stage 4 at TC39 🎂🎂🎂 Thanks to all the other champions of JavaScript's new date-time API. It has been a wild ride over many years! I wrote a blog post explaining how we got here 📜 bloomberg.github.io/js-blog/post...

Some time ago, @jonkuperman.com & @tchetwin.bsky.social had a dream for the JS engineers at Bloomberg to be more public about the cool JS work we have going on. That dream has come true - now we have a blog platform 🎉 (You'll see more articles over the next few days) bloomberg.github.io/js-blog/

Request volume to jsdate.wtf (from the nginx logs). Is this you state of the browser folks? 🥲

For those who were not in London today for State of the Browser 2026 conference, Josh relays @jason-williams.co.uk's talk!

It took a while, but the State of JS 2025 survey results are now live! 2025.stateofjs.com/en-US Thanks to @danielroe.dev for contributing the conclusion.

here's a brief look ahead at what we have planned in the e18e community for 2026 🎉 great collaborations, and many useful developer tools are in the works. also a huge thanks to all who contributed so far - many of the libraries, tools, and frameworks we use today are faster because of you 💙

Can’t wait for the first @e18e.dev and friends edition! ✨ Honored to host the show 🙌🏻

Your TypeScript year in review You "silenced" 417 errors with `as any` that turned into runtime errors as soon as the code ran TypeScript printed 4,693 error messages. 26 of them made sense You spent 98 minutes waiting for tsc to run. During this time you spent 544 minutes reading social media

this fall I worked with the core Git folks on writing an official data model for Git and it just got merged! I learned a few new things from writing it. github.com/git/git/blob...

Thanks @mmocny.com for the container timing shoutout and stealing my low effort diagram 😂 Great talk @ #perfnow

As an experiment, we (the Firefox team) wanted to try a new way to get feedback on which Interop proposals matter most. So, here's a web app where you can rank the proposals you care about, giving us data we can use when reviewing which ones to champion. interop-rank.jakearchibald.com

Glad to see TypeScript's Isolated Declarations feature already mentioned in three talks this morning at @viteconf.org 👍 It's one of the reasons tsdown and Oxc can generate Type Declarations so quickly ⚡ The main ID developer @titiancernicova.bsky.social is here if you wish to meet him.

Always happy to see something you worked on out in the wild! Love to see isolated declarations being used 😊. #viteconf.amsterdam

www.11ty.dev is now running Eleventy v4 alpha AROUND HERE WE TEST IN PRODUCTION (and also test on staging, previews, local, unit and integration tests in 12 different environments and JavaScript runtimes, but you get the idea)

Today I realized I’m going to be: – the 10th RM ever – the first Canadian RM, and – the first woman to serve in this role If you ask me, that’s all really, really cool.

Landed support for proxies in Node.js http/https builtins github.com/nodejs/node/... To enable proxies configured from *_PROXY env vars: use NODE_USE_ENV_PROXY=1. This was already implemented for fetch and released in 24 github.com/nodejs/node/... - soon the old builtins will also support it.

The 129th Ecma GA in Geneva on 25th June approved new recognition awards to people for their contributions and services. We at Igalia would like to congratulate our friends and collaborators @robpalmer.bsky.social and Michael Saboff for being awarded and thank them for their diligent work in TC39.

Ecma International Excitement 🎉 Last week, two TC39 members, Rob Palmer (@robpalmer.bsky.social) and Michael Saboff, received the Ecma Recognition Award for their contributions to Ecma, including TC39.

if you can, avoid exporting the types of a dependency. some of the migrations we've done are such a pain in terms of backwards compat because of this 😬
