ECMAScript excitement 😉 Congrats to @manishearth.bsky.social on unflagging TC39 Stage 3 Temporal in V8 today. Heading for Chrome 144 🎉 By many metrics this new date-time API is the single biggest change to JS ever 🔥 V8 uses Boa's temporal_rs by @jason-williams.co.uk Kevin Ness & Manish 👍

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

Boa v0.21 has been released! Plenty of new features, builtins and performance improvements. Blog post with details boajs.dev/blog/2025/10... Discussions: Lobste.rs: lobste.rs/s/upi3xa/boa... news.ycombinator.com/item?id=4567... www.reddit.com/r/rust/comme...

This is huge, Temporal is on its way, its been a long effort and great to see collaboration on a centralized Rust library including V8 who have never integrated Rust before now! Shout out to everyone who has been involved. Much more info in the blog post!

Hey thanks for the inclusion @infrequently.org, I feel honoured!

I’ve added support for the DAP “startDebugging” request in the Helix Editor. This means you can now debug JavaScript/TypeScript! It has been released in v25.07 helix-editor.com/news/release... PR: github.com/helix-editor...

Boa's temporal_js may turn out to be one of the most widely used implementations of the TC39 Stage 3 Temporal API 👍 An independent open source project having impact on the whole JS ecosystem. The Boa community has come along way since it was started by @jason-williams.co.uk seven years ago.

Interop 2025 launched today! Some really exciting features set to become part of Baseline this year.

I’ve been helping (alongside others) to Champion Temporal for around 6 years now, it’s great to see it approaching the finish line. The responses have been positive. Great work @joshcena.com and @meyerweb.com on the MDN documentation, momentous effort. Also props to the main man @ptomato.name

Myself and @pcwilliams.net continue to be humbled by the response we had at @perfnow.bsky.social. Our talk “Bloomberg Becomes Browser” has been published! You can watch it here: youtu.be/y1MCLZm8yAY?...

Fantastic to see @boajs.dev at the top of JS Weekly! Nice snake illustration too. There’s some good changes in this release and more coming up for 2025. “This is no toy engine” - javascriptweekly.com/issues/716 CC @cooperx86.bsky.social

We have released v0.20! This release includes more features, runtime additions, performance optimizations and more. boajs.dev/blog/2024/12... CC @thisweekinrust.bsky.social

Hello World!

In our meeting yesterday, we decided to adopt Element Timing (and the followup Container Timing work) into the working group. CfC coming up!! We also discussed some upcoming improvements to the crash reporting API (still in incubation). Minutes: w3c.github.io/web-performa...

Well that's made my day, jQuery was one of the first open source projects I ever contributed to (~2010!) 👋 @johnresig.com

Thanks to everyone at @perfnow.bsky.social for making us feel welcome and putting on a good conference. Really enjoyed meeting you all!

Crazy refreshing and insightful talk by @jasew.bsky.social & @pcwilliams.bsky.social at #perfNow! This could have continued for another hour only talking about the Container Timing API alone for my taste. Brilliant!

Today @jasew.bsky.social and I tell the story of how our team embedded web technology to give us the best combination of real-time data and rich UI for the #BloombergTerminal. It is an honour to speak at @perfnow.bsky.social. The #PerfNow team have been so welcoming. perfnow.nl/speakers#paulw

The @perfnow.bsky.social conference begins tomorrow in Amsterdam. It is going to be great 👍 For the first time @pcwilliams.bsky.social & @jasew.bsky.social will share the story of how the Bloomberg Terminal uses web tech & what this means for the wider web ecosystem 🎉 If you see us, come say hi 👋

Hello World!
