Using a while loop until right number was guessed between 1-6.

Here is a solution for this:

var randomNumber = Math.floor(Math.random() * 6 ) + 1;
var correctGuess = false;
var guess = prompt('I am thinking of a number between 1 and 6. What is it?');

while (!correctGuess)
{
  if (parseInt(guess) === randomNumber ) {
    document.write('<p>You guessed the number!</p>');
    correctGuess = true;
  } else {
//      document.write('<p>Sorry. The number was ' + randomNumber + '.</p>');
      var guess = prompt('I am thinking of a number between 1 and 6. What is it?');

  }

}

You didn't reference which course page you were working on. This code can be compacted a bit using a "do...while" loop. It could be that's what comes next in the course.

Another enhancement might be to allow a way out without guessing. Adding this code to the loop will let you quit by using the "cancel" button:

  if (guess == null) {
    document.write('<p>You gave up?   It was ' + randomNumber + '</p>');
    break;
  }
