Program Code – C++ with JavaScript: Combining Web Technologies

// Include necessary headers
#include <iostream>
#include <emscripten/emscripten.h>

#ifdef __cplusplus
extern 'C' {
#endif

// JavaScript function to be called from C++
EM_JS(void, js_alert, (const char* msg), {
    );
});

// Function to be called from JavaScript
extern 'C' void EMSCRIPTEN_KEEPALIVE c_plusplus_function(const char* input) {
    // Process the input in some complex way
    std::string processed_input = 'C++ Received: ';
    processed_input += input;
  
    // Call a JavaScript function from C++
    js_);
}

#ifdef __cplusplus
}
#endif

int main() {
    EM_ASM({
        // Define the JavaScript function to call C++ code
        if (typeof window !== 'undefined') {
            window.c_plusplus_callback = Module.cwrap('c_plusplus_function', null, ['string']);
        }
    });

    // Output to console
    std::cout << 'C++ with JavaScript Demo Running' << std::endl;

    // Intiate a C++ function call from JavaScript after 3 seconds
    emscripten_run_script('setTimeout(function() { window.c_plusplus_callback('Hello from JavaScript!'); }, 3000);');

    return 0;
}

Code Output:

C++ with JavaScript Demo Running

Code Explanation:

Our program serves as a bridge between C++ and JavaScript, showcasing their interoperation within a web technology context. Here’s the breakdown:

1. Headers: We utilize <iostream> for console I/O operations and <emscripten/emscripten.h> to access Emscripten functions.
2. Extern ‘C’ Block: This is crucial when combining C++ with C-style programming, like JavaScript. It disables C++ name mangling for compatibility.
3. EM_JS Macro: This Emscripten macro embeds JavaScript code in C++, creating js_alert, a function that calls JavaScript’s alert from C++.
4. c_plusplus_function: This function can be summoned from JavaScript. It processes incoming strings, representing sophisticated operations in a full-scale app.
5. Main Function: Launches the Emscripten-powered demo, defining a JavaScript function to trigger c_plusplus_function and using EM_ASM to integrate inline JavaScript code.
6. Console Output: Indicates the running status of our C++ program in the web console.
7. JavaScript Callback Setup: window.c_plusplus_callback is wired to the exposed C++ function. It’s available in the browser’s global scope.
8. Delayed JS to C++ Call: A JavaScript setTimeout is deployed to delay the call to c_plusplus_callback by 3 seconds, simulating an asynchronous operation.

Together, these pieces form a complex C++ app that interacts seamlessly with web technology, exemplifying a symbiotic relation between both languages in real-world applications.
