Guess the Number!

<script>
  let randomNumber = Math.floor(Math.random() * 10) + 1;
  let guessedNumber = false;

  function checkGuess() {
    let userGuess = document.getElementById('userGuess').value;
    if (userGuess == randomNumber) {
      guessedNumber = true;
      alert('You guessed the number!');
    } else {
      alert('Try again!');
    }
  }
</script>

<p>I'm thinking of a number between 1 and 10. Guess what it is!</p>
