You guys are sure this is the future of programming, right? 😕

The “State of AI 2026” survey just opened! This is run by the same folks who do the other "State of…" surveys, like JS, CSS, and React. The goal is to understand how web developers are using AI. So, whether you use AI or not, please take a few minutes to fill it out!

TypeScript 6.0 is now available! This release brings better type-checking for methods, new standard library features, new module features for Node.js, and more! But most important, this release brings us one step closer to the upcoming native-speed 7.0! devblogs.microsoft.com/typescript/a...

📮 In the first feature-length article on the Bloomberg JS Blog... @jonkuperman.com explains: 🗺️ what are source maps ✅ how he worked with others to standardize them in TC39 ✨ the new debugging features this unlocks

TypeScript 6.0 beta is now published! This release brings - inference improvements for functions - updates to package.json 'imports' - the Temporal APIs - alignments for the upcoming TypeScript 7.0 - & more! Try it today! devblogs.microsoft.com/typescript/a...

In today's episode of my life with adhd: Me Thursday evening: I'll go from the airport straight to the office on Monday. Musn't forget my badge. Also me Thursday evening: I'll take my personal laptop maybe I'll game a bit. I'll leave my work laptop at home. Not gonna use it over the weekend anyway

ECMAScript excitement 😉 Congrats to my coworker @ashley-c.bsky.social at TechAtBloomberg on advancing Await Dictionary to Stage 2.7 at TC39 today 🎉 Promise.all returns positional results as an array. Promise.allKeyed allows named results inside an object 👍 github.com/tc39/proposa...

So apparently in #node if you want to have a forked worker process not keep it's parent alive you have to: unref the child process, unref stout&stdin (by assuming they are Sockets! who knew?!) and on node 24 also call setKeepAlive(false) on them. Please tell me I'm doing this wrong! Anyone?

Guess what? Starting up new pocesses are expensive, especially when they run Javascript. Like really really expensive. Recycle your javascript processes, save the planet!

Reading a book and I love that there are twins named Vax and Vex.bBut as someone who struggles with names and often misread single letters in words.. I gotta say it's dam difficulty to keep the characters separate 😅 Guess they are just 'the twins' and hope the books makes sense with them as a unit 😅

The real Butlerian Jihad is not againt AGI, but against AI slop? Happy weekend to all www.youtube.com/watch?v=_zfN...

Its really lovely to walk around Amsterdam for a few hours after #viteconf

With declaration emit thanks to isolated declarations 😅

Night out after #viteconf.amsterdam

Writing JS plug-ins for rust based tools is solving a very big issue: people will soon be much less able to contribute to their own tooling since they won't have rust experience.

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

#viteconf.amsterdam excitement!

“The essential read” on GPT-5 and Sam Altman’s first major blunder. Well over 100,000 people have read it. Check it out!

🧩 @titiancernicova.bsky.social works at Bloomberg on TypeScript tooling and has contributed quite a few banner features to TypeScript. Check out his SquiggleConf 2024 talk on contributing Isolated Declarations, which makes TypeScript scale nicely for giant codebases. youtu.be/FJgzwgYXLRo

Expandable hovers 😍 Know these have been in the works for a while and I'm so excited to try them out. devblogs.microsoft.com/typescript/a...

This is so random! and muuuuch needed A new Random namespace with 22 methods for working with randomness in JavaScript. proposal just hit Stage 1

Lots of folks fell for the "DOM is slow" marketing of certain frameworks, but DOM isn't slow. *Uncontrolled style read-back* is. But what if that wasn't a thing? Looking for feedback on a new proposal to control layout thrashing here: github.com/MicrosoftEdge/MS…

summarizing the week of economics with my favorite comic of all time which happens to be constantly relevant

Same. I've always had a thing against cringe entertainment. And that just sounded like something I would cringe at because it was so over the top and so ridiculous at the time. Now? I'm sure it would feel like a random news show. We live in idiocracy times 😔

I agree a bit of selfishness is good. You need to put on your own oxygen mask before you help others. But what's happening today feels like some have put on their oxygen mask and are now collecting all the oxygen masks form everyone around and putting them in the shape of a helmet around their head.

Krebs: here's a detailed post on how our 1st Amendment rights are being attacked: krebsonsecurity.com/2025/03/how-... First commenter: omg wow you "got political" i guess it's time for me to leave, i can't believe i read your book and met you in person, who knew it would "come to this" 🤡🤡🤡

The cruelty may not necessarily be the point, but the self interest certainly is. And, well

I wish more people would say what DEI actually does:

Went to see a play in the weekend. A man for all seasons. One scene that seems so relevant for today: William Roper: “So, now you give the Devil the benefit of law!” Sir Thomas More: “Yes! What would you do? Cut a great road through the law to get after the Devil?”

TypeScript *earth-shattering* excitement 😉 The TypeScript team have rewritten the compiler in Go in order to optimize performance 🎉 🔹 10x faster type-checking 🔥 🔹 Uses significantly less memory This will hugely improve the TypeScript authoring & compilation experience.

FINALLY WE CAN SAY WHAT'S BEEN COOKING

This is such exciting new!

"The fever even seems to be breaking for the fiercely Atlanticist British press, for years behaving as if the UK is an American island just off the coast of Maine but now suddenly discovering themselves as European." Auch. But accurate.

Large amounts of ketamine can make anyone feel like they rule the world. When should Americans start worrying about Elon Musk’s regular use? Shayla Love reports:

There are three things that can never be combined: intelligence, decency and maga. If you’re intelligent and maga, then you’re not decent; if you’re decent and maga then you’re not intelligent; and if you’re decent and intelligent then you’re definitely not maga.

✨What a dream come true!✨ The co-creator of @typescriptlang.org himself, Anders Hejlsberg, took some time to look at the Doom project! We also had a chance to chat about other TypeScript topics more broadly - and that video will go live in a few days! DREAM. COME. TRUE.🚀

Enjoying the TypeScript life of Reilly in London 😉

📣 The SquiggleConf 2025 Call for Proposals is open! SquiggleConf is a conference for excellent web dev tooling. If you contribute to, make, or generally admire tools that help web developers be awesome, we want to hear from you. 💙 2025.squiggleconf.com/cfp #boston #squiggleconf #tooling #webdev

This is a must read.

TypeScript 5.8 now correctly detects this error (previously the whole ternary expression resolved to 'any' and it was missed), and a lot of you are going to be noticing it...

In your TS project, enabling verbatimModuleSyntax is highly recommended for predictable compilation If you haven't yet because of the errors it produces, I made an auto-fixer: github.com/privatenumbe...

ECMAScript excitement 😉 Congrats to TC39-TG4 @nicr.dev @jonkuperman.com @asumu.org on the approval of the brand new Source Map Format standard at the Ecma General Assembly 🎉 ECMA-426 specifies and clarifies the behavior of source maps used for JavaScript and other languages 👍

Airtable uses Oxc's Isolated Declarations implementation in their Bazel build to parallelize their type generation. 46x faster than without parallelism. Airtable is also one of the earliest adopters of ID, where they sent many PRs and issues to both tsc and oxc. medium.com/airtable-eng...

I think the problem is with how we view those kinds of exercises. I haven't needed those exact algorithms either, but I view them as a teaching tool. Learn to think algorithmicly.

It's been a bit over a week. Stopped tik tok, YouTube and X. Cold turkey. Nothing but a bit of BlueSky. Seems like if someone makes an app called FreshAir I might convince people I'm an outdoorsy person 😅
