Not sure I get the point of using a "flag" here.

Hi,

I'm not entirely clear on the purpose of using a "correctGuess" flag to break out of the loop. Can't the while loop be what is testing the condition of "guess" being equal or not to randomNumber? Here's what I have, and it seems to run fine:

do { guess = prompt("I am thinking of a number between 1 and 10. What is it?"); guessCount += 1;

} while ( parseInt(guess) !== randomNumber )

Am I missing something?

Thank you in advance for your response.

It would make the code more readable at first glance. Whilst your code is more compact, and would execute a few nanoseconds quicker, it is slightly more difficult to immediately understand what it does (admittedly, not much more difficult!).
