WebAssembly, or Wasm, provides a generalized, lightweight native binary format for any language that can be compiled to it. Once the source language is transformed into WebAssembly, that compact binary can run in a variety of contexts, from cloud virtual machines and desktops to IoT and mobile devices. One of the most interesting environments Wasm supports is the web browser. In this article, we’ll look at how to compile your Java code into WebAssembly, then we’ll run a demo application in a web server and see it in action.
