Function 没有进入第二个 if 块

Question

I want to read multiple lines from the stdin, unfortunately my code doesn't get past the first if block no matter which option I choose.

const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout,
});
function clientOpener(){
  rl.question("Choose a number:\n1)Start a bowling game\n2)Exit simulation\n", function (startGame) {
    const y = "1";
    const n = "2";
    if(y === startGame){
      (async () => {
        const playerCount = await rl.question("Ok how many players will there be (MAX: 8 players)\n");
        const parsedInput = parseInt(playerCount);
        if (parsedInput > 0 && parsedInput <= 8) {
            let listOfNames = [];
            for (let i=0; i<parsedInput; i++) {
                const name = await rl.question(`Enter name #${i}\n`);
                listOfNames.push(name);
                console.log(`Added ${name} to list of players\n`);
            }
            console.log(listOfNames);
        }
        rl.close();
      })();
    }
    else if(n === startGame){
      console.log("Ending interface");
      rl.close();
    }
    else {
      console.log("Please enter a valid option");
      clientOpener();
    }
  });
}
clientOpener();

Console output (same output happens for else if and else options):

1)Start a bowling game
2)Exit simulation

There are a few things that are going wrong in your attempt. One thing that is problematic is the fact that you are trying to use readlines question with await for which you need the readline/promises package that comes built-in with NodeJS. The code below uses the asynchronous version of readline and seems to be doing what you intended.

const process = require("process");
const readline = require("readline/promises");

const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout,
});

async function clientOpener(){
  let startGame = await rl.question("Choose a number:\n1)Start a bowling game\n2)Exit simulation\n");
  const y = "1";
  const n = "2";
  if(y === startGame){
    let playerCount = await rl.question("Ok how many players will there be (MAX: 8 players)\n");
    const parsedInput = parseInt(playerCount);
    if (parsedInput > 0 && parsedInput <= 8) {
      let listOfNames = [];
      for (let i=0; i<parsedInput; i++) {
        let name = await rl.question(`Enter name #${i}\n`);
        listOfNames.push(name);
        console.log(`Added ${name} to list of players\n`);
      }
      console.log(listOfNames);
    }
    rl.close();
  }
  else if(n === startGame) {
    console.log("Ending interface");
    rl.close();
  } else {
    console.log("Please enter a valid option");
    clientOpener();
  }
}

clientOpener();
