Software Engineer at Bloomberg. Opinions are my own.

[Tech At Bloomberg @TechAtBloomberg]

Our engineers @bloomberg have been contributing to the #JavaScript ecosystem for more than a decade. So, it's time they had somewhere to tell their story.

This week, we are setting up our new #JS engineering blog. More posts will follow soon!

@Rightpeg @james_sprt I think VS9 has left the gate again now

JavaScript top-level await is no longer considered 'baseline' due to a pretty big Safari bug https://t.co/YydXq4D8Sz

The module graph fails in cases where two modules import a third at the same time. Demo: https://t.co/ByzQqEseyu

It's best to avoid the feature for now 😔

[Rob Palmer @robpalmer2]

Ecma Recognition 😉

This award for my work as co-chair of @TC39 for the last five years was a lovely surprise 🙏

I'm grateful for the sustained encouragement & support from leadership at @TechAtBloomberg championing the value of open source & standards 👍

[Matt Pocock @mattpocockuk]

Here's why the Records and Tuples proposal died, and how Composites might solve it.

I did my homework for this one - I interviewed @acutmore, the Composites TC39 champion. And I'm really proud of how it turned out.

I'd love any feedback you can give me, and I'll make any necessary adjustments before it goes live.

@wunderacle @nodejs User friendly per the link you shared, with N-API version, V8 version, and ideally showing all patch versions denoting when a given line became LTS.
I think this was the state about 3 years ago and I struggle to find some of that data now, was it moved elsewhere?

[Rob Palmer @robpalmer2]

✨ dtsx is a fast new DTS emitter for TypeScript.

It leverages tsconfig "isolatedDeclarations" to ensure that source code is sufficiently annotated with types.

TypeScript 5.7 beta is now available to try! Read up on what's new today! https://t.co/TOrTctVmb1

[Rob Palmer @robpalmer2]

TypeScript London is tomorrow 😮

After two new open source releases, here's the line up:

🔷 @alistaiir to kick us off
🔤 Stricli: Building Better CLIs
🪿 Porffor: Type-Driven Runtime Optimizations
👻 ts-blank-space: Faster TypeScript Compilation

And some very special guests 💙

[@molisani.bsky.social @Zairex]

I'm excited to announce Stricli, a brand new #opensource framework for building type-safe, lazy-loaded CLI applications with #TypeScript.

We developed this framework for our internal CLIs at @TechAtBloomberg, and now we want to share it with the world.

@andywingo @igalia Now w/ 20+ years SpiderMonkey experience, ~15 v8/Node, Chromium etc. we’ve assembled one of the best sets of passionate JS ecosystem engineers in NYC/London.

London! Go meet Rob (TC39 co-chair) and everyone doing amazing things with JS/TS in London HQ on Wednesday!

[Jake Bailey @andhaveaniceday]

TypeScript 5.7 will load 2.5x faster than TypeScript 5.6 when run in Node 22+, thanks to @JoyeeCheung's work to provide an offical API for V8 compile caching.

That's 60% less time waiting for tsc/tsserver to actually start doing work.

[Ashley Claymore @acutmore]

Today, I'm releasing a TypeScript compiler called ts-blank-space 🎈

We use this at @TechAtBloomberg to perform type-stripping on a modern subset of TypeScript.

It's written in TypeScript and is fast because it uses whitespace to enable work-skipping.

[Tech At Bloomberg @TechAtBloomberg]

We're hosting our first London #TypeScript Community Meetup at @Bloomberg's EMEA HQ in London on Wed., October 2 (18:00 BST).

Join us for 3 exciting talks & to meet London @typescript community members, including some TypeScript contributors.
