The author begins by acknowledging a comment made on Reddit about leveraging Zig’s WASI support to simplify the process of building WASM modules. They mention that using Clang for compilation is still useful for certain reasons. The author then proceeds to explain how to crack open a WASM module to understand its contents. They provide an example of a compiled program and break down the sections of the WASM module, including the preamble, type section, function section, memory section, and global section. They also explain LEB128 encoding for integers in a WASM module. There is no controversial or surprising information in this content.
