Although similar questions have already appeared, following theirs instructions I obtain an error. So my code is as follows

var readline = require('readline').createInterface({

input: process.stdin,

output: process.stdout

});



    var name;

    readline.question(`What's your name?`, (name))

        readline.close()

and as a result I have

{ RequestError: Syntax error, permission violation, or other nonspecific error

at StreamEvents.req.once.err

Do you know what is wrong? I'm using npm readline package

According to the documentation, the second argument should be a callback function. What you currently have is an uninitialized variable. To fix it, you could do something like this:

const readline = require('readline').createInterface({

    input: process.stdin,

    output: process.stdout

});



const response = function (name) {

    console.log('Hello ' + name);

};

readline.question(`What's your name?`, response(name));

readline.close();

(I'm using const instead of var to adhere to ES6 standards for JavaScript/Node)

The second argument of question should be a callback function

readline.question('What's your name',(name)=>{

    console.log(name)

});
