Yesssss github.com/microsoft/Ty...

Trivia question - how many errors are reported by TS here? (:

@jakebailey.dev ported my perf-oriented PR to TS-Go and it helps quite a bit (%-wise) there too! This is nice github.com/microsoft/ty...

Weird trivia learned while looking through v8's source: function fn(a) { console.log(a) } fn.toString() // 'function fn(a) { console.log(a) }' const bound = fn.bind(null) bound.toString() // 'function () { [native code] }'

People: lockfiles are important! People: uses github/action@v1 Me: uses github/action@v1 🫠

A prerelease of Changesets v3 is out! Some code and dependency cleanups so far, with more minor breaking changes soon, but should be simple to upgrade. Thanks to @andarist.bsky.social for helping to make this happen. github.com/changesets/c...

@searyanc.dev what's the proper mental model when it comes to void's presence in unions and intersections? and how it should behave when those are narrowed down by CFA etc? I can't find comprehensive answer to this anywhere

I have one bad habit I don't like: I'm trying to fix every issue I find in my node_modules I have one good thing to say about myself: I'm trying to fix every issue I find in my node_modules

Once again I reminded myself how awesome Replay and time-travel debugging is. True game changer - I'd be hunting this bug for hooours without it.

I convinced my wife to get a Macbook...

> Unable to evaluate expression: call is only supported with topmost stack frame 🫠🫠🫠 I hate this sooo much

I have some serious pull requests porting to do 😂 github.com/microsoft/Ty...

I couldn't believe this thing when I first heard about it and I'm truly amazed that Dimitri had so much stubbornness in him that he stuck with it and made it happen

I feel like I'm abusing implementation details of TypeScript just a little bit too much here 🤣 github.com/statelyai/xs...

I just had to alias `util` to `node:util` using Vite's aliasing option. Life is beautiful

I've intentionally used default case in switch/case on non-last position for the first time in my life, AMA github.com/thysultan/st...

This was an interesting dive for me into how TS constructs its control flow information, I played a couple of times with interpreting its pieces in the narrowing-related code, but I almost never had a need to change how its created: github.com/microsoft/Ty...

I had it lying on my machine since August, it's time to tie 2024's loose ends 😅 so I finally got myself to push it out and open a PR cc @colinhacks.com @ssalbdivad.dev @effect-ts.bsky.social github.com/microsoft/Ty...

JS class private fields trivia #1 - you can access them in subclasses as long as those subclasses are defined within the superclass

OSS is weird, I maintain packages that I don't even use at all nowadays

nice experimentation by @jfet97.bsky.social going on: github.com/microsoft/Ty...

I'm supposed to be good at TypeScript but typing generic wrappers around React.forwardRef is... 🫠

Inspired by @tkdodo.eu, I opened a PR with a codefix proposal to add "missing" awaits into return statements in async function enclosed by try statements github.com/microsoft/Ty...

Like it or not, this is how art is born

I'm reading v8 source code to understand how promises are created and chained internally... what my life has become

We Just Gave $750,000 to Open Source Maintainers 🥳 blog.sentry.io/we-just-gave...

And btw... this was shipped by one and only @gabritto.bsky.social

I'll remember the world before and after this PR: github.com/microsoft/Ty... The new era of conditional types checking is coming in TypeScript 5.8!

I still find surprising type behaviors in TypeScript. This one makes sense but I had to think about it for a moment to understand how it can be explained: www.typescriptlang.org/play/?ts=5.7...

Filip cooked something really nice here

My PR adding support for package.json#imports in import statements got merged in recently. I think it made the cut for 5.7 just before the RC so it will be in the final release! github.com/microsoft/Ty...

This looks neat ✨

Wow, this got busy. I’m not even using this app (yet?) and I see an influx of hundreds of new followers in the past days

Partial inference through _ sigil at call site got scheduled for TS 5.2 🎉 https://github.com/microsoft/TypeScript/pull/26349#issuecomment-1536633920

Lol, this thing has no giphy integration yet. How do they even dare to call this a product
