WebAssembly from Scratch: From FizzBuzz to DooM

Exploring WebAssembly from scratch from a backend-person-point-of-view. A story in four acts.


Welcome to my journey where I will explore some WebAssembly. We will start from scratch. My goal is to look at everything bottom-up, without much magic tooling or frameworks on our way. In this article, I prefer to build everything as much from scratch as possible.

Non-goal: We will not implement our own WebAssembly interpreter or runtime, but use existing ones, e.g., wabt or the Chrome and Firefox browsers.
