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

- 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)
