Question

The assignment is "Create a file named histogram.js. Write a program that will allow me to enter numbers between 1 and 100. I will enter numbers until I enter 0. Iterate over the array and display a histogram for the numbers entered. Don't overcomplicate the histrogram piece. Displaying the histogram only involves printing an asterick for the number of times a number is contained in the array."

i wrote a program but i cannot run it, my program is:

const readline = require('readline');

const rl = readline.createInterface({

input: process.stdin,

output: process.stdout

});

const arr = [];

rl.question('Enter a number between 1 and 100 (or 0 to quit) : ', (num) => {

arr.push(parseInt(num));

while (num !== 0) {

if (num >= 1 && num <= 100) {

arr.push(num);

}

rl.question('', (num) => {;

arr.push(parseInt(num));

rl.close();

});

for (let i = 1; i <= 100; i++) {

let count = 0;

for (let j = 0; j < arr.length; j++) {

if (arr[j] === i) {

count++;

}

if (count > 0) {

console.log(i + ": " + "*".repeat(count));

}

}}

rl.close();

});

Can you help me fix this.
