## What it is
A collection of code examples accompanying the MDN WebAssembly documentation, written in WebAssembly text format (.wat) and compiled to .wasm. It serves as a hands-on reference for learning WebAssembly concepts.

## Use cases
- learn webassembly basics with runnable examples
- understand the wasm text format
- find example wat files to compile with wat2wasm
- study webassembly features like multi-memory
- accompany mdn webassembly tutorials with working code

## When to choose
- you are learning WebAssembly and want examples tied to MDN docs
- you need small reference .wat snippets to experiment with
- you want CC0-licensed sample code to reuse freely

## When to avoid
- you need a production WebAssembly library or runtime
- you want a build toolchain rather than example code
- you need maintained application code rather than teaching samples

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools
- domain: developer-tools, tutorials, web-development
- platform: browser, wasm, cross-platform
- tags: webassembly, examples, documentation, wat, mdn, education
