WebAssembly is a binary instruction format for a stack-based virtual machine that allows code from languages like Rust and C++ to run in the browser and on the server.
A simple function is written in WebAssembly Text (WAT), compiled to a binary Wasm file using wat2wasm, and then executed from a JavaScript host.
An Advent of Code example demonstrates how all operations, from memory loads to arithmetic and comparisons, use the stack to pass arguments and receive results.
WebAssembly modules operate on a dedicated linear memory block for security, and they communicate with the host environment through defined imports and exports.
The WebAssembly System Interface (WASI) provides a standard API for modules to access system resources like file I/O and networking, which are not available in core Wasm.
The Q&A covers practical topics including when to use Wasm over JavaScript, the WebAssembly Component Model (WIT), and approaches to debugging and profiling.
