Launch HN: I wrote a book about WebAssembly Hey HN! I've been working on a book about WebAssembly over the last few months, and it's finally available at http://levelupwasm.com ! Why a book on WebAssembly you ask? Well... WebAssembly is awesome (obviously ) but it's certainly not the easiest thing to learn. So I wrote this book as a practical intro to using WebAssembly in your web apps. I would appreciate any feedback! more
