Do While loop - Simply add numbers

Question

I need to prompt the user to enter a series of numbers, or the word "quit". Then, If the user enters a number, add the new number to a running total. And, If the user enters the word "quit" the loop should stop execution. I cant figure what should I do here. Im a beginner. i don't know how to make it work when user enter a word quit

let total = 0;
let number = 0;
do {
 total += number;
 number = parseInt(prompt('Enter a number: '));
 if (number >= 0) {
 document.writeln("<p>You entered " + number + "!</p>");
 } else {
 if (isNaN(number)) {
 number = parseInt(prompt('Enter a number: '));
 document.writeln("<p>Try again. We are looking for a number!</p>");
 }
 }
} while (number >= 0)
document.writeln("<p>The total is " + total + "</p>")

• Rickard Elimää: Just a heads up. The loop breaks if you enter a letter two times in a row.

Answer 1

Use break to stop the javascript loop:

let total = 0;
let number = 0;
 do {
 total += number;
 text = prompt('Enter a number: ');
 if (text == "quit") {
 break;
 }
 number = parseInt(text);
 if (number >= 0) {
 document.writeln("<p>You entered " + number + "!</p>");
 } else {
 if (isNaN(number)) {
 number = parseInt(prompt('Enter a number: '));
 document.writeln("<p>Try again. We are looking for a number!</p>");
 } 
 }
 } while(number >= 0)
 document.writeln("<p>The total is " + total + "</p>")
