while (randomNumber !== guess) { guess = getRandomNumber(upper); attempts += 1; }

while (randomNumber !== guess) { guess = getRandomNumber(upper); attempts += 1; }

I don't understand how this one works

while (randomNumber !== guess) { // loop while the random number is NOT equal to the guess
    guess = getRandomNumber(upper); // get a new random number and set the guess variable to this new number
    attempts += 1; // increment the amount of guesses
}

// any code after this block will be run once the random number IS equal to the guess.

Basically, you're just looping until the computer "guesses" the correct number. And every time it makes a new guess, it adds 1 to the attempts variable. So that you could say something like "In 14 attempts, the correct number was guessed!"

I see we store the new getRandomNumber(upper) we get after each time the computer is wrong and store it to guess. I was thinking that guess was equal to getRandomNumber(upper) while it was not equal. I was like what.
