In this screen, we will compile a simple C++ program into WebAssembly using Emscripten. This program is going to output a message Hello, WebAssembly! in the console.

Let's start by writing the C++ code:

1#include <iostream>
2using namespace std;
3
4int main() {
5  cout << "Hello, WebAssembly!";
6  return 0;
7}

We will examine the steps of compiling this C++ program to wasm in detail in the upcoming screens. Understanding this process is crucial as it forms the basis of integrating performance-critical scenarios such as physics simulations or heavy computations into web applications. This undoubtedly opens numerous possibilities for a web developer, particularly those having a decent amount of web development coding experience.

As a senior engineer, you are likely to appreciate how WebAssembly allows us to leverage the advantages of C++, and bring its efficiency to the web.
