javascript - 使用 readline 在 javascript 中进行一系列用户输入，其中相应的问题存储在数组中

Question

我在数组 var questions=[] 中存储了一些问题。我使用 forEach 遍历数组并获取每个问题的输入并将其显示在终端本身上。但它只问第一个问题，显示响应并停留在那里。它不会转移到下一个问题。我应该使用 rl.close()，但是在哪里。这是我的代码 Quiz.js。

const readline = require('readline');

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

var questions=[
  "Hi, What is your name?",
  "I need your contact number also",
  "Thanks! What is your favourite color?"
];

questions.forEach(myFunction);

function myFunction(item, index) {
  rl.question(item, (answer) => {
    console.log(`You said: ${answer}`);
  });
  rl.close(); //THIS IS IMMEDIATELY CLOSING AFTER THE FIRST QUESTION
}

请纠正我。

您想要一一提出问题，然后在提出所有问题后close()。

const readline = require('readline');

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

let questions = [
    'Hi, What is your name?',
    'I need your contact number also',
    'Thanks! What is your favourite color?',
];

(async () => {
    let answers = [];

    // asking questions one by one
    for (let question of questions) {

        // wait for the answer
        let answer = await new Promise(resolve => rl.question(question, resolve));
    
        console.log(`You said: ${answer}`);
    
        answers.push(answer);
    }

    // close at the end
    rl.close();

    console.log(answers);
})();
