My code works fine, my question is, is my code good example for the work environment? Thank you!

(function() {
  function makeQuestion() {
    var num1 = Math.floor(Math.random() * 11);
    var num2 = Math.floor(Math.random() * 11);
    var result = num1 * num2;

    function askQuestion() {
      var answer = prompt(num1 + " * " + num2 + " = ").toLowerCase();
      if (answer !== 'exit') {
        if (answer == result) {
          alert("correct");
          makequestion();
        } else {
          alert("wrong");
          makequestion();
        }
      }
    }
    askQuestion();
  }
  makeQuestion();
})();
