# Section Summary
> This lesson covers compiling C/C++ and Rust applications into WebAssembly, including tools, techniques, optimization, debugging, and security best practices.
In this lesson, you’ll explore the end-to-end process of compiling C/C++ and Rust applications into WebAssembly (WASM). We start with an overview of the major compilers and build tools, then dive into hands-on demos and advanced techniques:
* Overview of the WASM toolchain & compiler internals
* Hands-on C/C++ to WASM with [Emscripten](https://emscripten.org)
* Building and packaging Rust modules via [wasm-pack](https://rustwasm.github.io/wasm-pack)
* Optimizing WASM output for size and speed
* Debugging strategies for tracing and profiling WASM modules
* Secure coding best practices for sandboxed WebAssembly
Throughout this lesson, focus on both development efficiency and runtime performance to deliver high-quality WebAssembly binaries.
## Learning Objectives
By the end of this section, you will be able to:
| Task | Description |
| ------------------- | -------------------------------------------------------------- |
| Compile source code | Translate C/C++ and Rust projects into optimized WASM binaries |
| Use Emscripten | Set up and run Emscripten for browser and Node.js targets |
| Leverage wasm-pack | Build, test, and publish Rust-based WASM packages |
| Analyze performance | Employ profiling tools and code tuning for faster WASM |
| Debug modules | Apply source-map debugging and stack inspection techniques |
| Secure your modules | Implement sandboxing and input validation for safe execution |
Always audit third-party modules and enforce Content Security Policy (CSP) to mitigate potential WebAssembly security risks.
