I tried to do the code before it was shown to me and did the 'do while' loop as follows:
do { guess = prompt("Guess a number between 1 and 10"); guessCount += 1; } while (parseInt(guess) !== randomNumber)
This seemed to work absolutely fine. However, Dave's code is longer . So I am wondering, is there an issue with the way I have done it? Or is it fine and Dave is just trying to show a different way of escaping a loop?

Your solution of directly testing the exit condition in the loop is more concise; and in my opinion, perfect for this particular situation.
Good job!
