WebAssembly from Scratch is an educational and exploratory project that demonstrates how WebAssembly works from the ground up by progressively building increasingly complex programs starting from simple examples like FizzBuzz and culminating in advanced applications such as running classic games. It is structured as a narrative journey that emphasizes understanding WebAssembly at a low level, rather than relying on high-level tooling or abstractions. The project walks through writing WebAssembly manually using the text format, then compiling from languages like Rust, and eventually integrating larger codebases into WebAssembly environments. It is designed primarily for backend developers or systems-oriented engineers who want to understand how WebAssembly operates internally, including compilation, memory layout, and execution. The repository includes multiple stages and examples that illustrate different approaches to building and deploying WebAssembly modules.
