如何让 rl （或提示）返回用户输入的值

Question

How can I get rl.question to return the value that the user inputs, my code looks like this:

 const readline = require('readline'); const { stdin: input, stdout: output } = require('process'); const rl = readline.createInterface({ input, output }); console.log(rl.question("hello?",(answer) => {return answer}))

I know there are probably better modules to use if I want a python-style input function, but 'prompts' seems to have the same problem.

I'm not super sure what you are asking, so let me know if this isn't it.

ReadLine Docs

To console.log() the answer from a ReadLine question there are multiple methods, here are some.

try moving the console.log inside of the {}

rl.question('hello? ', (answer) => {
 console.log(answer);
 // ... whatever you want to do with the answer variable 
})

or you can use async/await with promise

async function AskQuestion() {
  return new Promise(async (resolve, reject) => {
    rl.question('Hello? ', (answer) => {
      resolve(answer);
    });
  });
}

and then just await the function somewhere

(async () => {
    let answer = await AskQuestion();
    console.log(answer);
})();
