What is wrong with this code?

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 that?');
    guessCount +=1;
    if (parseInt(guess) === randomNumber {
        correctGuess = true;
    }
} while ( ! correctGuess );
    document.write("<h1>You guessed the number!</h1>");
    document.write("It too you ' + guessCount + ' to guess the number ' + randomNumber);

It's a bit hard to read without code formatting, but it looks like you have an if statement with a missing close parenthesis:

  if (parseInt(guess) === randomNumber    // <-- ")" needed here

Also, you have a string that starts with a quote but ends with an apostrophe ("single quote"):

document.write("It too you ' + guessCount + ' to guess the number ' + randomNumber);
//             ^ mismatch  ^
