🤖 Try Autopilot (Preview) in VS Code!
With Autopilot enabled, the agent stays in control of the workflow. It can run tools, retry on errors, and continue working until the task is complete.

ECMAScript Euphoria! 🎉
We don't always post when a single proposal advances, but when we do, it's Temporal -> Stage 4.
Just days shy of 9 years from Stage 1, a herculean effort on the part of many champions, delegates, invited experts, and contributors, past and present. Thank you all! 🙌
ECMAScript EXTRA-SPECIAL excitement 😉
🚨🚨🚨 IT'S ABOUT TIME! 🚨🚨🚨
Congrats to @ptomato.name on advancing Temporal to Stage 4 at @tc39.es today 🎉
Temporal is the replacement for the JavaScript Date API 👍
![Code example showing the usage of Temporal.ZoneddateTime
```js
// London DST starts: 2026-03-29 01:00 -> 02:00
const zdt = Temporal.ZonedDateTime.from(
"2026-03-29T00:30:00+00:00[Europe/London]",
);
console.log(zdt.toString());
// → "2026-03-29T00:30:00+00:00[Europe/London]"
const plus1h = zdt.add({ hours: 1 });
console.log(plus1h.toString());
// "2026-03-29T02:30:00+01:00[Europe/London]" (01:30 doesn't exist)

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 📜

Source maps are a vital part of modern web development, but the lack of a standard made it impossible for us to add new features or improve the debugging experience.
This is the story of how we standardized source maps and how we continue to ship features through standards 📜

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 🎉

Announcement about the new modal editor. > We are experimenting with a new modal editor experience for editors that you typically open briefly and then return to your active task. A modal editor floats on top of the editor without impacting the layout of your editor tabs. To close the modal editor, press Escape. The modal has an action to move the editor back into an editor tab, as well as an action to maximize the modal experience.
Also, I am a huge fan of the new modal editors - settings no longer have to open as a dedicated tab.
It's still experimental but I think it makes a lot of sense for quickly modifying settings.
Some other awesome stuff in these announcements:
🖼️ Kitty graphics terminal rendering (i.e. pictures in your console!)
🧬 Unified settings for JavaScript+TypeScript
🐍 Python Environments Extension is stable (works across env managers, includes uv integration)

"tsgo caught type errors that the JavaScript implementation didn’t catch! I adopted tsgo in 20+ projects ranging from 1,000 to 1,000,000 lines of code, and it has improved iteration speed quite a bit."

Some pretty awesome improvements in 1.26 for compiling/testing typescript-go.
With a clean build/test cache, running the full test suite used to take 3m45s, but now takes just 2m10s.

Our tsgo adoption at Vanta has been pretty high-impact. Everything is so, so much faster now.

reddit comment with the contents "i've been waiting for typescript 6, hopefully it fixes the annoying issues i've been having with 5, specifically the whole module resolution thing"
Probably as specific as anyone really needs to get
"You know, I actually don't hate it anymore. It's actually pretty good."
Glowing endorsements from my Python friends. 🥰
