Am I the only one who found the options to this question confusing? None of these is consistent with the TS39 "Type Annotations" (aka "Types as Comments") proposal. Erasable types should be _ignored_ (like comments) at runtime.

Also… please take the survey! 🚀

#JavaScript #TypeScript #StateOfJS
Screenshot of State of JavaScript Survey question regarding types: How would you like to see types implemented natively in JavaScript? • Runtime types: Types that are parsed at runtime by the browser. • Type annotations: Compiler-level TypeScript-like type annotations that get stripped during bundling. • JSDoc-like types: JSDoc-like types written as code comments. • I would not like to see them implemented • Other…

Doorbell rings, rapid knocking. Rush to the door to find Amazon package… but… ZERO sign of delivery person. Like… VANISHED 💨! Are they a NINJA 🥷?! ⬇️
Man at front door looking around puzzled, searching empty suburban landscape for missing delivery person. Amazon package on doorstep.

"tearing-by-default" = me every time I see @rich-harris.dev and @adamrackis.bsky.social arguing on BlueSky 😢
#svelte #solidjs #react #rainbowsandunicorns
Screenshot of two Bluesky posts discussing framework differences. The first post by rich harris mentions using 'await' without boilerplate and criticizes 'tearing-by-default.' The second post by Adam Rackis questions where the tearing occurs in the Solid version.

3+ months since Svelte Summit … missing Spain … made Tortilla Española 🇪🇸. Not that difficult tbh (except maybe "the flip" 😅), and soooo worth it 😋. #SvelteSummit #Spain
A golden-brown tortilla española on a white plate, sitting on a red and white checkered tablecloth. The thick Spanish potato omelet has a beautifully cooked surface with characteristic wrinkles and golden coloring. A plated serving of tortilla española cut into a wedge, accompanied by a slice of bread topped with red tomato spread and a small salad of fresh arugula greens. The meal is presented on a white plate on an outdoor dining table.

Request for comments…

The TSTFU Principle: 90% of coding in TypeScript is writing code that works. The other 90% is convincing the type checker to STFU.

Venn-pie chart showing TypeScript development time: two overlapping 90% sections labeled 'working code' and 'type checker STFU', with most of the circle showing blended colors representing simultaneous effort on both tasks.

Actually got to use Runed FSM to orchestrate animations in my Svelte MDR implementation (as demoed at Svelte Summit 2025). It's a joy to work with – kudos! github.com/kenkunz/svel...

Where would MDR be without Svelte? Sputtering along on a "virtual DOM"?? Lumon expresses gratitude to @rich-harris.dev and the Svelte community for eliminating developer suffering. May more experience the joy of truly refined, un-severed web development. #svelte #severance #lumonislistening

Indeed – a horrible violation of the Principle of Least Surprise. This is why we can't have nice things! If only Matz had designed JavaScript... 😢
Code sample follows pattern of original post with additional test cases demonstrating `100 == box` and `box == 100` while `box != boxSame`.

Debugging the MDR interface and accidentally created this gem. Wouldn't want to withhold this expression of Cheer from the world. (Regrettably, floor refiners lack clearance to view.) Praise Kier. #benevolence #cheer #dataserveskier #svelte
