alert from WebAssembly (WASM)
This very simple and minimal tutorial documents in a few easy steps how to play with WebAssembly (WASM) and get first results within minutes.
While the code below is mostly useless, it will show, how to call the
alert function from within a WASM file and thus demonstrate how to import and export DOM objects.
Of course, this exercise has no real use. It is just meant to show, that getting started with WASM isn't hard. And there is no need for a complex build-chain, tons of tools or a dedicated VMs. Just use a browser, one online tool and that's it.
