A Custom WebAssembly Compiler

The article describes the author's project to create a static type checker and a custom WebAssembly compiler for their toy language, nodots, without using existing toolchains. It explains the process of traversing an abstract syntax tree to emit WebAssembly Text (WAT) format, highlights a performance comparison showing a 4000x speedup over a tree-walk interpreter, and provides technical examples of the compiler's output and design.
