A compact binary format, resulting in smaller file sizes and faster loading times.
A stack-based virtual machine, providing efficient execution of code.
A linear memory model, simplifying memory management for compiled languages.
Compiling Code to WebAssembly
To leverage WebAssembly in your web applications, you'll need to compile your source code (e.g., C, C++, or Rust) into a WebAssembly binary format. There are several tools available for this purpose, including:
Emscripten: A popular toolchain for compiling C and C++ code to WebAssembly.
Rust: A systems programming language with built-in support for WebAssembly compilation.
AssemblyScript: A TypeScript-like language that compiles directly to WebAssembly.

Debugging WebAssembly Code
Modern browser developer tools provide support for debugging WebAssembly code. Source maps enable you to view and debug the original source code (e.g., C, C++, or Rust) instead of the compiled WebAssembly code, making the debugging process more intuitive.
