javascript - 我想记忆一下 readline 。怎么做？

Question

我想记忆一下

rl.question("input your port do you want (about 0 - 65535) : ", function(portnumber)

在此之后:

if(netinfo > 6665){
    return console.log("Error stupid i say about 0 - 65535")
}

rl.question("input your port do you want (about 0 - 65535) : ", function(portnumber){
   if(netinfo > 6665){
     return console.log("Error stupid i say about 0 - 65535")
    } 

     netinfo = portnumber;

     const requestHandler = (request, response) => {  
      console.log(request.url)
      response.write('<b>welcome to groone simple http server :p </b>');
      response.end('ahahahahahah :)');
    }

怎么做？

我看到的唯一方法是递归:

(function restart(){
  rl.question("input your port do you want (about 0 - 65535) : ", function(portnumber){
    if(portnumber > 6665){
       console.log("Error stupid i say about 0 - 65535");
       return restart();
    }
    //...
  });
})()
