A place for advanced TypeScript to call home.
~60% Fable cost cut by transparently turning the code into an image and having the model OCR it. WILD idea. also hilarious. github.com/teamchong/px...
we got pattern matching in JavaScript (well.. Flow) before gta6 medium.com/flow-type/ja...

livestream reminder: the full technical deep dive on the Doom in #typescript types codebase is happening tomorrow at 1pm Eastern with Dillon Mulroy hosting. let us know if there's anything specific you'd like to have covered!
🤔 what if we normalize apps embedding in-depth in-context docs that (if expanded) teach the concepts.... but with the user's own data? new (pretty chunky) page just landed in today's TypeSlayer release:
🥳 TypeSlayer is out! celebrate by posting what your type graph looks like! it legit has an actual leaderboard now: so bonus points if you win lol 🏆🏆 run: `npx typeslayer` source: github.com/dimitropoulo...
this is a sorta interesting difference between javascript and rust. something something values vs references
![use std::collections::HashMap;
fn main() {
let mut x: HashMap<Vec<i32>, i32> = HashMap::new();
x.insert(vec![1], 0);
x.insert(vec![1], 0);
x.insert(vec![1], 0);
assert_eq!(x.len(), 1);

cross platform native apps: they take longer but at least they're more complicated
hands down, best feedback so far: "this should have a leaderboard". we're talkin' multi-gigabyte json trace files lol.
⚔️introducing TypeSlayer⚔️ A #typescript type performance benchmarking and analysis tool. A summation of everything learned from the benchmarking required to make the Doom project happen. It's got MCP support, Perfetto, Speedscope, Treemap, duplicate package detection, and more.
new project launching tomorrow: 1. no, definitely wont be as cool as Doom (lol) 1. types-level-super-nerds will enjoy it - everyone else won't care 1. here's a screenshot (these are #typescript types)

This week on the pod, we talk to Dimitri Mitropoulos (of @michigantypescript.com) about building DOOM in the TypeScript type system. We walk through all the nitty gritty and explore this truly amazing engineering feat! You'll be surprised! typescript.fm/13 #doom #typescript
Honk once if you want pipelines to progress to stage 2.7 at TC39 this week
if you ever need to smile, just remember that @nicknisi.com owns typescript.dad and was very excited about snagging it

we all missed a golden opportunity in today's AMA with TypeScript team to ask "types vs interfaces" and "explicit vs implicit return types"
typescript-go is now a performance benchmark for the Go compiler! go-review.googlesource.com/c/benchmarks... an interesting finding from the AMA the team is hosting now on the TypeScript Community Discord.

happening now, and it's REALLY interesting to see the technical questions and answers
TypeScript@typescriptlang.org · last yr.Starting soon! 📢 We've got a TypeScript AMA starting in just a few minutes (10am Pacific) on the TypeScript Discord! discord.gg/typescript
the "why not Haskell!?" folks really fell down on the job yesterday.
hot off the press: an excellent statement from Anders, creator of C#, about choosing Go over C# for this project
never forget that if the announcement were "we cured cancer!" some people will still respond "yeah, that's cool and all, but my buddy is a cancer researcher and now they're out of a job, you jerks!!!"
If someone in the TypeScript world wants to really drive the point home, a way would be to open checker.ts and checker.go next to each other and show how similar they are. It's uncanny. This was the right move.
your @typescriptlang.org just got 10 times faster. We sat down with Anders Hejlsberg to ask questions library authors, power users, tooling makers, and compiler contributors might have.

✨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.🚀
