C++ Function

emscripten::val LoadScript(emscripten::val scriptpath)
{
    using namespace emscripten;
    String hash = scriptpath.as<String>();
    if(!val::global("VMain")["Loaded"][hash].isUndefined())
    {
        auto promiseCallback = [&](val resolve, val reject){
            resolve(hash);
        };
        return val::global("Promise").new_(js::bind(promiseCallback, std::placeholders::_1, std::placeholders::_2));
    }
    auto promiseCallback = [&](val resolve, val reject) -> void{
            resolve();
            val script = val::global("document").call<val>("createElement", val("script"));
            auto  -> void{ //NOT EXECUTED - check errors
                emscripten_console_log("On load");
                resolve(hash);
            };
            script.set("onload", js::bind(onloadCallback)); //No errors here 

            auto  -> void{ //NOT EXECUTED - check errors
                emscripten_console_log("On error");
                reject(hash);
            };
            script.set("onerror", js::bind(onerrorCallback)); //No errors here
            
            script.set("src",scriptpath);
            script.set("type", val("text/javascript"));
            val::global("VMain")["Loaded"].set(hash, val(true));
            val::global("document")["body"].call<val>("appendChild", script);
    };
    return val::global("window")["Promise"].new_(js::bind(promiseCallback, std::placeholders::_1, std::placeholders::_2));
}

Original JS Code.

window.VMain = {};
window.VMain.Loaded = [];

window.VMain.LoadScript = function (scriptPath) {
    if (window.VMain.Loaded[scriptPath]) {
        return new this.Promise(function (resolve, reject) {
            resolve();
        });
    }
    return new Promise(function (resolve, reject) {
        var script = document.createElement("script");
        script.src = scriptPath;
        script.type = "text/javascript";
        window.VMain.Loaded[scriptPath] = true;
        script. () {
            resolve(scriptPath);
        };
        script. () {
            reject(scriptPath);
        };
        document["body"].appendChild(script);
    });
};

Thanks for your help.
