Ohhh this is cool: github.com/dy/jz
JS syntax that compiles to pure WASM. No runtime, no GC.
"Wasm with TypeScript" oh hey that's us!!
Is it the end of February already??
Yes, yes it is. Which means we just sent out our #Wasm tidbits.

In case you missed it last week, @dubroy.com was on CodeTV to show to talk about #Wasm with @jason.energy.
It was a lot of fun! Worth a watch if you missed it live.
New post on the @ohmjs.org blog —

v18 is now more than 50x faster for real-world grammars while using about 10% of the memory 🔥
…this post goes into the details of how it's built.
Tomorrow at 17:20 CET / 12:20 EDT / 9:20 PDT, I'll be livestreaming at twitch.tv/jlengstorf, teaching @jason.energy about WebAssembly!!
I'll do my best to condense the best parts of our Wasm book (@wasmgroundup.com) into ~60 minutes. 😄
Spritely Hoot, our Scheme->WASM compiler (and all-around WASM toolkit) hits 0.8.0, and this one is a BIG release! spritely.institute/news/hoot-0-...
For the first time you can LIVE develop web applications using Hoot, from the comfort of your own editor! See the video at the top!
Ep 56 is live! 🎙️ npmx.dev, Chrome 145 DevTools, WASM with TypeScript, and why OSS maintainers need breaks. Plus: fun with generics & how to pronounce "Knip".

No worries! Check out our conversation on the Web Dev Podcast, then code along with us on Learn with Jason.

Its common to only hear Wasm talked about in contexts that seem… advanced. How can mere mortals like us hope to build with it? Patrick Dubroy talks about flattening the learning curve and putting…
A while back, someone in the @wasmgroundup.com Discord asked about resources for learning the formal notation used in the WebAssembly spec.
One I like is Jeremy Siek's "Crash Course on Notation in Programming Language Theory": siek.blogspot.com/2012/07/cras...

News for the week of Feb 16, 2026: npmx.dev is a better frontend for npm, Chrome 145 includes some cool new toys, and we figure out that Knip is pronounced with a hard-K. From the community: fun with...
