5,523 Pointswhy can't i just write "while (guess !== randomNumber)" instead of creating a boolean ? worked for me
var randomNumber = getRandomNumber(10); var guess; var guessCount = 0;
function getRandomNumber( upper ) { var num = Math.floor(Math.random() * upper) + 1; return num; }
do { guess = prompt("enter a number between 1 and 10"); guessCount+=1;
if (parseInt(guess) === randomNumber) { break; } } while ( guess !== randomNumber)
document.write("The random number was " + randomNumber + " it took you " + guessCount + " trys");

} while (parseInt(guess) !== randomNumber);
But the purpose of the lecture is to show how boolean variables can be used, and the original code gives a clear example. As a "best practice" developer, you'll employ your skills to create code that's both clear and efficient, but in the courses you can expect the teachers to occasionally forgo efficiency when illustrating a particular principle.
