Typescript enthusiast (ask me about TS). I work at Bloomberg in JavaScript Infrastructure & Tooling . Opinions are my own.
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 👍

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 😅

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 ⚡

🧩 @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.

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:

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 😔
So, I've never actually seen Idiocracy. From what I've heard tho, it's a pretty amazingly accurate documentary about the current administration.

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.

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?”
