Our previous exploration of WebAssembly (Wasm) helped us understand its immense impact on web development. Now, we delve into a central aspect of working with Wasm: Compiling C++ code into wasm modules. This might initially seem daunting, especially if you're not very familiar with C++, but worry not! We're walking you through every step.

C++ is a general-purpose programming language formed as an extension of the C language with additional features such as classes, which aid in supporting the object-oriented programming concept. The aspect of interest here is that C++ has robust low-level capabilities, making it a good candidate for conversion into Wasm bytecode.

Wasm modules are units of Wasm code that encapsulate your compiled C++ functionalities, ready to be executed in the browser. Transition from C++ to Wasm isn't plain sailing, but isn't an uphill climb either. It entails a systematic process of installing the right tooling, writing some C++ code, and following through with the correct compilation commands.

Fret not if this seems overwhelming. As we move forward, you'll get a hands-on understanding of this process, ensuring you're well equipped to compile your own C++ code into wasm modules. Remember, the aim is to leverage the benefits of efficient, powerful low-level C++ code in the high-level web environment!

using namespace std;

int main() {

  cout << "Executing your first wasm module generated from C++ code.";

  return 0;
