# Prototype
Link for compiling code with Embind → https://emscripten.org/docs/porting/connecting_cpp_and_javascript/embind.html
**Command for compiling code with Embind:** ```emcc -lembind -o test.js test.cpp -s NO_EXIT_RUNTIME=1 -s "EXPORTED_RUNTIME_METHODS=['ccall']"```- **EMSCRIPTEN_BINDINGS** macro is used to bind the C++ function to make it callable from JavaScript (https://git.pranger.xyz/varnicas/testingwasm/src/branch/main/C++/test.cpp#L12-L15)
- Emscripten compiles the C++ code to WebAssembly, generating a **.wasm** file and **JavaScript** glue code that loads the WebAssembly module and sets up the bindings
- When the HTML page is loaded, **test.js** is executed, loading the WebAssembly module , Emscripten's Module object is created, exposing the C++ functions (like myFunction) to JavaScript
- Example of using **Module**: var result = Module.myFunction(input)
