Thanks so much @mattpocock.com for discombobulating! Great writeup

OMG, it works! Simply changing the interface from method shorthand syntax to object property syntax makes the desired squigglies appear!

typescript interface wat typescript interface wat. GitHub Gist: instantly share code, notes, and snippets.

@mattpocock.com in your capacity as typescript whisperer, have you blogged about "function parameter bivariance"? I'd be curious if you have practical advice how to avoid the problem I describe in this gist gist.github.com/pesterhazy/4...

Vibecode, not too much, mostly UI

I could use a nice trip to somewhere in Europe or the UK.

I'd like to sponsor my trip by doing useful work with your company. I have a lot of skill and experience in software delivery, code craft, and team management.

Consider contracting me for a few days. I would love to help.

Delfonics?

Exciting. Btw I noticed on iOS Chrome, the back button seems borked

Oftentimes a library will do a lot more than what you need, creating accidental complexity. Expert teams recognize this

True it depends. The answer may be different depending on, among other things, the team's skill level

Talking about an app, not a lib

Today should a node project use ESM (rather than commonjs) and {"type": "module"}?

Just spent half a day fighting with node's module resolution and --experimental-strip-types

Zod v4 is marketed as having 20x fewer instantiations of tsc...

While it's great to see progress, this news makes me hesitant to use it. Why was it doing so much in the first place? All that type-level complexity must have a cost

Logged in to Twitter, the first thing I see is this

Pathetic

Cover of the book “Exploring TypeScript”: • TS 5.8 edition • A book for JS programmers by Dr. Axel Rauschmayer The cover shows an old mechanical typewriter with a German key layout whose brand is “Continental”.

My new book is out: “Exploring TypeScript”. It’s free online!

• About 75% of the content is new or rewritten.
• Most of the new content is about computing at the type level.

#TypeScript

Congrats!

What a wonderful finale, just as cynical as I hoped it would be

Are US tariffs going to affect digital goods like SaaS software?

I didn't get it, why would a semicolon be expected?

Haha yeah TS is hyperpragmatic. It's part of its appeal

Learning TypeScript is easy, mastering Javascript, with its years of cruft, is the harder task

I haven't read this but the author is great exploringjs.com/tackling-ts/...

Execute Program Learn it. Code it. Remember it.

For TypeScript specifically, I'll recommend this course (not a book sadly) www.executeprogram.com

Spooky but I prefer it

Updating JS dependencies after 6 months. Nothing works
