If you are interested in a hands-on way to learn #wasm, check out the book that @marianoguerra.org and I wrote together!

Excited to announce the official launch of our online book, WebAssembly from the Ground Up! 🎉
It's the book we wish we'd had 3 years ago.
No messing with tools and frameworks. It's a hands-on guide to the core of Wasm: the instruction set and module format.
Link below. 👇
