WebAssembly

## Understanding WebAssembly in Browser Utilities WebAssembly (WASM) is a W3C standard that enables C, C++, Rust, and Go code to be compiled into compact binary modules that run inside modern web browsers alongside JavaScript. ### Key Security & Privacy Advantages 1. **Sandboxed Memory:** WebAssembly executes inside an isolated memory sandbox managed by the browser engine, preventing unauthorized access to local host files. 2. **Zero Network Requirement:** WASM binaries run entirely offline without communicating with cloud servers. 3. **Near-Native Performance:** Enables industrial compression codecs (like MozJPEG, libpng, and SQLite) to process multi-megabyte files in milliseconds directly on user devices.
