Who This Book Is For

This book is for anyone who wants to build web applications. Whether you have had just a little bit of JavaScript exposure or whether you are a seasoned professional with dozens of React and Redux applications under your belt, WebAssembly has the potential to change the way that you build apps and the power of those applications in a way that few technologies before ever have.

Whether you consider yourself a front-end, back-end, embedded, or any other kind of developer—this book is for you. Compiling other languages to WebAssembly means you get to use familiar development life cycles and toolchains and build and test strongly-typed, powerful code.

Finally, if you think that there is more to this WebAssembly thing than just the web applications, then you will enjoy this book as well as we build WebAssembly interpreters in Rust and run them on Raspberry Pis to control hardware via GPIO. WebAssembly holds a lot of promise for many different types of developers, including the promise of unifying back- and front-end coding experiences.
