## What it is
An open-source book, 'WebAssembly friendly programming with C/C++', teaching Emscripten-based WebAssembly development with C/C++. The repo hosts the bilingual (Chinese/English) source of the book, which has also been published in print.

## Use cases
- learn how to compile C/C++ to WebAssembly with Emscripten
- understand WebAssembly memory and module concepts
- port existing C/C++ libraries to the browser
- find Emscripten best practices and examples
- study WebAssembly interop with JavaScript

## When to choose
- you want a structured tutorial on C/C++ WebAssembly development
- you are starting with Emscripten and need practical guidance
- you prefer a free open-source book with bilingual content

## When to avoid
- you need a tool or library rather than learning material
- you work with Rust or Go instead of C/C++
- you need up-to-date coverage of the newest WebAssembly features

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: wasm, compiler, documentation
- domain: tutorials, web-development, programming-languages
- platform: wasm, cross-platform
- tags: emscripten, webassembly, c-cpp, book, open-source-book, web-server
