WebAssembly in Action

"Atwood's Law” is driven by the idea that all applications will ultimately wind up on the web and therefore must be written in JavaScript. WebAssembly may be your way out! With WebAssembly, you can write in nearly any modern language and run your code in the browser through a memory-safe, sandboxed execution environment that can be embedded in a web browser and other platforms.

Getting set up and moving with WebAssembly requires you to modify your web dev process; WebAssembly in Action will get you started quickly and guide you through real-world examples and detailed diagrams that help you create, run, and debug WebAssembly modules.

About the technology

WebAssembly compiles code written in C, C++, Rust, and other highlevel languages into an ultra-compact bytecode files that run in the browser and other environments at near-native speeds. Besides vastly improved performance, opportunities to reuse existing code, and the freedom to build in your favorite language, this game-changer allows access to newer and faster libraries. WebAssembly is the joint effort of industry leaders like Microsoft, Mozilla, Google, and others, with
