## What it is
A curated awesome-list cataloging programming languages that compile to WebAssembly or have their virtual machines implemented in WebAssembly. Entries are organized by production readiness, from in-production languages like C, C++, Rust, and Go to experimental and unmaintained projects.

## Use cases
- find a programming language that compiles to WebAssembly
- compare wasm language maturity before choosing a toolchain
- research which languages run in the browser via wasm
- discover experimental languages targeting WebAssembly
- check whether my language has a wasm backend

## When to choose
- you need a reference of wasm-capable languages sorted by stability
- you are evaluating languages for browser or edge deployment
- you want a starting point for WebAssembly ecosystem research

## When to avoid
- you need a compiler or toolchain itself rather than a list
- you need guaranteed up-to-date or officially maintained documentation

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, compiler, wasm
- domain: programming-languages, web-development, compilers, awesome-lists
- platform: browser, wasm, cross-platform
- tags: awesome-list, webassembly, curated-list, compilation-targets
