Input number of players, then creating array of players using number?

Question

var n
var players = []

var rl = readline.createInterface(process.stdin, process.stdout);

rl.question("Enter number of players ", function(answer) {
    //Use number of players to generate array of player names

for (n = 0; n < parseInt(answer); n++) {
    var playerNumber = n + 1
    rl.question("Enter name of player " + playerNumber, function(answer) {
        players.push(answer)});
// stops prompting after asking for name of player 1?
    }

});
    rl.close;
rl.on('close', function(){

console.log("The players are: " + players.toString());
});

This works until “Enter name of player 1”, which the code stores the value of. Code does not prompt the rest of the players. Why?

I also tried replacing it with the ‘for’ loop with a ‘while’ loop, but it came out even worse. It does not even begin prompting for the name of player 1. Why so? Help is appreciated :) thanks everyone

var readline = require('readline');
var n
var players = []

var rl = readline.createInterface(process.stdin, process.stdout);

rl.question("Enter number of players ", function(answer) {
    //Use number of players to generate array of player names

while (n < parseInt(answer)) {
    var playerNumber = n + 1
    rl.question("Enter name of player " + playerNumber, function(answer) {
        players.push(answer)});
    n++;
// does not even start prompting name of player 1?
    }

});
rl.close;
rl.on('close', function(){

console.log("The players are: " + players.toString());
});

Edit: Tried moving rl.close out of the loops. The issue is still the same, this is what shows up in my console:

Enter number of players

(Input) 4

Enter name of player 1

(Input) Player 1

(Console stops prompting, when I tried adding more names and ending the process, the array only stores the name of player 1.)

You could solve this using recursion and callbacks:

const readline = require('readline');

var n
var players = []

var rl = readline.createInterface(process.stdin, process.stdout);

function readPlayers(playerCount, playerArr, curr = 0) {
    if (playerCount == curr) {
        rl.close();
        return;
    }

    rl.question("Enter name of player " + (curr + 1) + ": ", function (playerName) {
        playerArr.push(playerName)
        readPlayers(playerCount, playerArr, curr + 1);
    });
}

rl.question("Enter number of players: ", function (answer) {
    //Use number of players to generate array of player names

    readPlayers(parseInt(answer), players);
});

rl.on('close', function () {
    console.log("The players are: " + players.toString());
});

Here rl.close is called only once when the readPlayers end recursion condition is met.
