 fetch(apiURL, setting)
     .then(loadRes)
     .then(logger)
     

     function loadRes(res){
       console.log("loadRes is called");
       return res.json();
     }
     

     function logger(reply){
       stringReply = JSON.stringify(reply);
       //console.log("The JSON String " + stringReply)
       return new Promise(resolve => {
         setTimeout(() => {
           resolve(stringReply);
         }, 2000);
       });
     }

     async function asyncCall(){
       const result = await logger(reply); // a string value i.e "Hello World"
       console.log(result); //for testing
     }

How do I retrieve the value of stringReply and place it in the app.post from a Express module

app.post('/', function( req, res){
 res.send(); // 
}

When a value is obtained in function logger(reply) , I would want it to be able to send it to res.send().

I have tried putting res.send(asyncCall()) but it does not work.

Whenever I call asyncCall(), I would expect a string value.
