Node excitement 😉 Congrats to @marcoippolito.dev on making it official: type-stripping in Node 25 is now declared to be stable 🎉 You can run: node index.ts The capabilities have not changed since Node 24. This is purely a maturity indicator.

A four-panel comic shows a worried man saying, 'We're cooked, AI will take over.' A robot responds, 'Generate an apple.' In the next panel, the robot presents a hamburger instead. In the final panel, the man smiles with relief, realizing AI won’t actually take over.

🤔 Did you know the language barrier between JavaScript and C++ is becoming history? WebAssembly is doing what Java once promised: true "write once, run anywhere" - but this time it's actually working. 1/4 🧵

🧠 Linear memory is WebAssembly's bridge between worlds — it's how Wasm modules share & manipulate data, following the same mental model C/C++/Rust developers know and love. Want to master these core concepts? Dive into my hands-on Wasm course at 👉 learn-wasm.dev #WebAssembly

This looks great, and seems like the perfect compliment to our book! Ours is a step-by-step guide to building a small compiler for a toy language, using the *binary module format*. @d3lm.bsky.social's course will teach you the text format (.wat) with interactive exercises. Why not both? 😄

Ever wondered how allocators work? Learn WebAssembly explains all of this in an interactive and fun way. Not only does it come with interactive components like these but also includes tools like a memory inspector to really understand how each instruction changes memory.
