    let code = wait (() = > {
        const browserifyObject=browserify();
        browserifyObject.add(`${__dirname}/game.js`);
        return new Promise <string > ((resolve, reject) = > {
            browserifyObject.bundle(error,source)=>{
                if(error){
                    reject(error);
                    return;
                }
                const code = new TextDecoder().decode(source);
                resolve(code);
            });
        });
