The code is a histogram using stars (astericks), I need to take user input (using readline.sync) and the out put shows in rows the astericks and the columns are the numbers that where typed in going straight down, at the end after entering the zero to stop the program. It goes from 1-100 for the number that can be entered by the user if they want to quit they must enter 0. I am very confused on the looping system when it comes to arrays and my book doesn't help me very well. My array needs to start at index 0, and add 1 to the index. And I was told to use the max function. I was also told to not over complicate the histogram, the histogram display only involves printing an asterick for the number of times a number is contained in the array. This is what I have at the moment, and I'm still working on it.   const readlineSync = require('readline-sync'); let arr =[]; let num = readlineSync.question("Enter a number between 1 and 100, or enter 0 to exit: "); while (num !== "0") { //while loop console.log("The number you entered is " + num); num++; } for (let i = 0; i <= 100; i++) { //for loop if (num >= 0 && num <= 100) { //if statement arr.push(num); if else (num ===i) { console.log(("* ".repeat(i) else{ console.log(" "); } } } }

I am writing code for javascript. The code is a histogram using stars (astericks), I need to take user input (using readline.sync) and the out put shows in rows the astericks and the columns are the numbers that where typed in going straight down, at the end after entering the zero to stop the program.

This is what I have at the moment, and I'm still working on it.

const readlineSync = require('readline-sync');
let arr =[];
let num = readlineSync.question("Enter a number between 1 and 100, or enter 0 to exit: ");

while (num !== "0") { //while loop
console.log("The number you entered is " + num);
num++;
}

for (let i = 0; i <= 100; i++) { //for loop
if (num >= 0 && num <= 100) { //if statement
arr.push(num);
if else (num ===i) {
console.log(("* ".repeat(i)
else{
console.log(" ");
}
}
}
}
