WebAssembly, despite its name, is far more useful than just as a stack-based virtual machine (VM) for web browsers. It's increasingly being used to address a wide variety of programming needs from cloud-native computing, edge computing, mobile development, and edge-based projects. To help you master it, the Linux Foundation is now offering a free online training course, called WebAssembly Actors: From Cloud to Edge (LFD134x).
In particular, though, this online class is designed for developers who already have experience in building microservices and cloud-native application development. In short, this is not an introduction to WebAssembly. But, if you're ready to build, experiment, and test locally Functions as a Service (FaaS), this class is for you.
You will learn about you can add on to the basic WebAssembly specification with community tooling and open source projects. When all's said and done you'll clearly understand how to build WebAssembly-based applications and how they really work.
You can audit the class for free to audit on edX.org for seven weeks. You can also get a verified certificate of completion for $149. The latter includes a full year of course access.
