5,301 Pointswhy do you increase it by 1 += 1; for a guess? just wondering
do { guess = prompt("I am thinking of a number between 1 and 10. What is it?"); guess += 1; } while ();

Is this part of a course? Please provide a link to the course page you are working with.

5,301 Pointsyes sorry here's the full version
=====================================
var randomNumber = getRandomNumber(10); var guess; var guessCount = 0; var correctGuess =false;
function getRandomNumber( upper ) { var num = Math.floor(Math.random() * upper) + 1; return num; }
do { guess = prompt("I am thinking of a number between 1 and 10. What is it?"); guessCount += 1; if (parseInt(guess) === randomNumber) { correctGuess= true;

243,656 PointsThe second code doesn't seem complete either, but there's enough there to tell that guessCount is being used to keep track of how many guesses are made. So for each guess, it is increased by 1.
Then, after the loop ends, guessCount will have the number of times the loop repeated.
