JS² compiles JavaScript to WebAssembly ahead-of-time, sandboxing untrusted modules in your supply chain – running in JS engines or standalone – no interpreter or engine bundled. Goal: 100% ECMAScript & NPM compatibility; Method: spec/test-driven agile team of agents against spec + 100.000 unit tests, passing 75.4% of test262 in a JS host, 43.8% standalone. Module sandboxing limits blast radius for supply chain attacks or AI generated code Lightweight with no bundled interpreter or engine, starting at 100 bytes Fast, typically being an order of magnitude or more faster than interpreters or engines without JIT embedded in the module Garbage Collection natively supported by Wasm 3.0, builtin and robust instead of avoiding or embedding Help us bringing this vision of a new substrate for running JavaScript as lightweight, composable modules to life – by reviewing, testing, contributing, or donating! js2.loopdive.com @loopdive #JavaScript #TypeScript #WebAssembly #sandboxing #security

JSCraftCamp 2026 registration is open! Munich's finest open space is back! Experience the registration via a GitHub PR! Contribute ideas and sessions to get the most out of it! Two full days of free learning, connecting and thoughtful discussions: jscraftcamp.org

@Winterr4077 @css_battle We're learning so much every time when doing CSSBattles at VirtualCoffee.io, it's really nice to solve them in a group and learn from each others solutions and ideas!

This just happened 👀

Was das wohl für ein neues Produkt ist, was mir da auf @ntvde verkauft werden soll...?

@rahulv_dev @vuejs @nuxt_js Could a blur filter for the background improve readability? But looks like a nice stab at it already. In Apple's video, it looked like they changed the frontend text colors based on the background, not sure how will that's possible. Cool demo though! Session for #jscc25? 😉

What do you think about this Liquid Glass component for @vuejs & @nuxt_js ? Not perfect though! Coming soon to Inspira UI...

@dummdidumm_ Not me. 🫤 But maybe at the JSCraftCamp? The (free!) #jscc25 registration opens when Svelte Societies' ticket sale closes. Coincidence? 😉

See you there?

@opensas @dummdidumm_ I thought tabs vs spaces was settled after someone mentioned accessibility advantages for tabs (which made me embrace the change from spaces to tabs) 😅

@dummdidumm_ common guys, we have more important stuff ro think about we still haven't figured out if we should use tabs or spaces, types or interfaces, vim or vscode, ...

New year, same old boring Twitter discussions

What?! I sent this post through my laptop, but the image was sent from my phone through the #Flottform browser extension? 🤯

@rauchg @vercel @storyblok Why does a CDN proxy help them for their older stuff that is not migrated yet?

@NarigoDF @vercel @storyblok smart!

The Met museum runs on @vercel. You're gonna notice some pages are buttery smooth to transition to… enter the magic of App Router giving you fast initial load, but with app-like transitions.¹ Some others take longer, like "Art > Curatorial Areas" below. And that's fine. What they're doing is using Vercel as CDN proxy to the old monolith while the transformation continues. This is exactly how I'd do it, and even how we migrated @vercel from Pages Router to App Router. Remember: there's two types of migrations: incremental, and failed ones. ¹ Frameworks like @nextjs, @sveltejs⁠kit, @nuxt_js, embrace this. Fast transitions ftw!

We definitely need a checklist for our marketing efforts 😅

@ShopifyDevs As a student, I worked on a browsergame in the middle of the night after partying. Can't remember the issue I produced, but I do remember the quote we had in our Best-of-IRC thread: I should always code drunk, so at least I have something to do the next day! Does that qualify? 😅

when bugs appear, the duckie appears pair program with our new debugging buddy built for those 3am coding sessions what’s your craziest debugging story? we may send a quacky surprise your way 🦆

it's here svelte.dev/blog/svelte-5-…

@ShopifyDevs Probably Flottform.io to simplify upload of product images + a remove background from image if that doesn't exist already 😅

If you could add any API to Shopify, what would it be?

@wengel_ca @samjshore Nice, I've done this for German, but instead of definitions, it gives you words that (may) rhyme: npmjs.com/package/reimem… I've used it over here: sprechakt.de/reimemonster I couldn't find a way to get the meter - if you have suggestions on how to know something's a Jambus... 😅

@samjshore I thought about making something like this, here were some more features to fully complete it: - syllable counting (per line/word) - left-click for definition/synonyms - word rhym panel Mostly cause I've been doing poetry recently and all these tools in one app would be useful.

Should I ship this??

Parallax cards with masked blurs v2 ✨ – DeviceOrientation – Progressive blur/masked layers with CSS sin() – Adapts to landscape with media queries 🤙

@normanmaurer (and safe travels btw 😅)

@normanmaurer Where are you heading? How's life over there? 🙂

Looking forward for some coding while flying back to Germany …. See you again soon California
