WASM is not quite a stack machine
🚀 WASM's Hidden Depths: Understanding its Non-Stack Machine Nature
WebAssembly (WASM) is often misunderstood as a simple stack machine, but in reality, it offers a more complex and versatile architecture that enables efficient execution of code across different platforms, making it a powerful tool for building high-performance web applications with languages like C, C++, and Rust. Its design allows for a sandboxed execution environment, enhancing security and compatibility.
