Question

How can I create a JavaScript loop that continuously prompts the user for input until they type "exit"?

Can you help with a JavaScript challenge? I am looking to create a loop that continuously asks the user for input until they type "exit". Once they do, I want the program to display the minimum value that was entered.


var students = prompt("Enter Student Name: ");
var studentArr = new Array(students);

var mark = parseInt( prompt("Enter Student Mark: ") );
var markArr = new Array();

function min (mark){
    var min = Number.MAX_VALUE;
    for(var i = 0; i < mark.length; i++){
       if(parseInt(mark[i]) < min)
           min = parseInt(mark[i]); 
    }
    return mark;
}
var smallest = min(mark);

document.write(smallest);

Answer №1

Give this a shot:

let input = prompt("Please enter a number");
let min = parseInt(input);

while (input !== "exit") {
    input = parseInt(input);
    if (input < min) {
        min = input;
    }
    input = prompt("Please enter another number");
}
alert(min);

This is the basic code for finding the minimum number. You may consider adding some additional checks to ensure the input is a valid number.
