In an AI writes the code world, how important is knowing the fundamentals well? Things like language feature, using the right data structures and algorithmic thinking.

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

TIL: 1<<30-1 has different precedence in go vs js. Go sees it as (1<<30)-1 while js sees it as 1 << (30 - 1). Conclusion: use () whenever it get complicated. They are free. Gonna wait for THE MERGE before I open a PR 😅. Cc: @andrewbran.ch
Building upon the fine work of @pier.fumagalli.org / @titiancernicova.bsky.social / @andrewbran.ch I've been throwing copilot at the new TypeScript 7.1 API and ts-loader. Very early days but some progress! github.com/TypeStrong/t...

📮 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
Jon Kuperman@jonkuperman.com · 6mo agoSource 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 📜 🧵
![A JSON file representing a source map. The code contains:
{
"version": 3, // Always the integer 3
"file": "out.js", // Optional: name of the generated file
"sourceRoot": "", // Optional: prefix prepended to each entry in "sources"
"sources": ["foo.js", "bar.js"], // Required: list of original source URLs/paths (or null)
"sourcesContent": [null, null], // Optional: inlined source text, aligned with "sources"
"names": ["src", "maps"], // Optional: symbol names referenced by "mappings"
"mappings": "A,AAAB;;ABCDE", // Required: encoded mapping data (base64-VLQ deltas)
"ignoreList": [0] // Optional: indexes into "sources" considered "third-party"

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 😅

With declaration emit thanks to isolated declarations 😅
Rob Palmer@robpalmer.bsky.social · 11mo agoVite+ unified CLI will bring together many existing features and a new monorepo task runner.
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.
Titian Cernicova-Dragomir@titiancernicova.bsky.social · 11mo agoAlways happy to see something you worked on out in the wild! Love to see isolated declarations being used 😊. #viteconf.amsterdam
