How would I change the value of randomNumber each time?

I've been trying to make it so that each time the number was incorrectly guessed, it would also change. Mostly just to have a better understanding of the code and how it works. Unfortunately I can't figure it out and I'm hoping someone here can tell me. Thanks!

Hi Kelsey! This is what I did to change the randomNumber each time (and I wrote it to the screen just so I knew the random number before I guessed so I could test for what happens when the number is guessed correctly). I also set i<=50 since the loop could really go on infinitely if the person never guesses correctly! I also deleted the const randomNumber declaration at the top of the document since we want to be able to change it for each loop iteration.

for (i=0; i<=50; i++) {
  let randomNumber = getRandomNumber(10);
  document.write(randomNumber);
  guess = prompt('Guess a random number between 1 and 10');
  if (randomNumber == guess) {
    main.innerHTML = '<p> You guessed the number!</p>';
    break;
  } 
}
